When RadEditor is configured with RenderMode="Auto", it renders fine on a mobile, but the Find and Replace throws a JavaScript error:

Render mode configuration in the web.config

<add key="Telerik.Web.UI.RenderMode" value="Auto" />
It seems, code is looking for FindAndReplace key in this._dialogDefinitions, but it's not there. However, the key FindAndReplaceSettings is there.

The Delete and Backspace buttons remain enabled in spell check mode, allowing the client to delete selections inside the Editor's content area.

Steps to reproduce:
1. Open http://demos.telerik.com/aspnet-ajax/editor/examples/spellchecker/defaultcs.aspx
2. Click the Spell check icon
3. Select several words from the content and press Backspace/Delete

Result: The selected content is deleted
Expected: The Delete/Backspace button press is ignored

The Bold, Italic, Underline, Justify, Indent, Outdent and other commands are not localized in the Undo/Redo dropdowns.

We have an issue where the RadEditor context menu for <td> element doesn't get displayed. It throws a "Permission Denied" error. Within <td> the table toolbar is not functional either. 
To reproduce: In an aspx page, create an updatepanel with a LoadContent button, RadEditor and Save button.
1. Click on Load Contents button
2. RadEditor with text "Loaded" will get displayed
3. Insert a table
4. Go to a table cell and verify context menu for td shows fine
5. Click Save
6. Go to a table cell and right click - context menu doesn't show (If you have IE developers tool, you will see "Permission Denied" error.)

ASPx page:
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
    <asp:UpdatePanel ID="upd" runat="server">
        <ContentTemplate>
              <asp:Button ID="btnLoad" runat="server" Text="Load Contents"  OnClick="btnLoad_Click"  />
              <telerik:RadEditor ID="HTMLEditor" runat="server"></telerik:RadEditor>          
                <asp:Button ID="btnSave" runat="server" Text="Save"  OnClick="btnSave_Click" UseSubmitBehavior="false" />
        </ContentTemplate>
    </asp:UpdatePanel>     
</asp:Content>
C# Code:
 protected void Page_Load(object sender, EventArgs e)
        {
        }
        protected void btnSave_Click(object sender, EventArgs e)
        { 
            HTMLEditor.Content = HTMLEditor.Content + " updated";            
        }
        protected void btnLoad_Click(object sender, EventArgs e)
        {
            HTMLEditor.Content = "Loaded";
        }

Content font famility is changed when a word is spell checked in Chrome in Windows 7.

Steps to reproduce:

Paste the following content in this demo: http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx

<span id="ctl10_supportMessagesRepeaterControl_repeaterMessages_ctl11_lblMessageText" class="text"><span style="font-family: Arial; font-size: small; background-color: #ffffff;">Dear Telerik&nbsp;</span><br style="font-family: Arial; font-size: small; background-color: #ffffff;" />

When the fore/backcolor of the Editor is changed through its toolbar, the same color is set to all Editors on the page. The problem is reproducible in Lightweight rendering.

Clear content;
Add a table;
Open context menu by selecting a cell in the table;
Open Cell Properties;
Open More cell Styling;
Chose Background color;
Change it and click OK
Click OK in Table Wizard.
Actual: No background color is applied. 

Even if the ToolsFile is pointing to a valid file, no toolbar is rendered when the control is loaded in a mobile browser.


Run the following code in Chrome's mobile emulator:
<!DOCTYPE html>

ImageManager's layout is broken in Bootstrap in Lightweight:
https://www.screencast.com/t/Sdu2XbqVh11b

Steps to reproduce:
1. Open http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx?skin=Bootstrap

2. Open the ImageManager dialog

I recently updated my website with the dll patch telerik  provided for the cryptographic weakness:
http://www.telerik.com/support/kb/aspnet-ajax/details/cryptographic-weakness?utm_medium=email

After the update I found that the pages which were using the RadEditor control and several other controls was not loading and throwing this error:
Parser Error Message: Decryption key specified has invalid hex characters.

Several other controls are throwing this error but I cannot delete controls one by one and check which ones are having this problem.

But I checked for the RadEditor and it was throwing this error. Nothing else is there on the page while testing other than this control.
This does not happen on a plain new website and is happening when we have the sql mermbership and machine key configured. We are using passwordFormat as encrypted in sql membership config and cannot remove machine key.
If you got to test it, then test it on some already configured machine key and sql membership website.

I have attached screenshots for this error and telerik dll patch in use currently.

We are on a production server and we need a solution for this issue ASAP.

When track changes disabled the backspace is OK:
- User typed two lines (1) & (2)
- At the beginning of the line (2) user presses the backspace key, it successfully appended the line (2) with line (1) (where there was a space available). 
When track changes enabled the backspace does not work as expected:
- User typed two lines (1) & (2)
- At the beginning of the line (2) user presses the backspace key, it removes the end of the character in line (1).

The CSS styling for copied tracked text remains after the track changes are accepted is Chrome.

Video: https://www.screencast.com/t/Ul565rfo


Steps to reproduce:
1. Open http://demos.telerik.com/aspnet-ajax/editor/examples/trackchanges/defaultcs.aspx and clear the content in HTML mode
2. Switch to Design view and write some text
3. Copy this text and paste it into a new line
4. Click "Accept All track changes"

Result: The copied row remains styled as tracked text

Several JS errors are trown when writing in re-focussed empty Editor in Chrome.

Video:  https://www.screencast.com/t/Wx6Ucs8m6S5w

First error's message:
RadEditor.js:10521 Uncaught TypeError: Cannot read property 'startContainer' of null


Steps to reproduce:
1. Open in Chrome: http://demos.telerik.com/aspnet-ajax/editor/examples/trackchanges/defaultcs.aspx
2. Switch to HTML mode and clear the whole content
3. Switch back to Design mode
4. Click any of the Bold/Italic/Underline commands
5. Click out of the Editor's element
6. Click back in the Editor's content area and start typing

Result: JS errors are thrown

Workaround is to add the following function override at the end of the page (a sample is attached below)
				Telerik.Web.UI.Editor.Utils.isWindowDestroyed = function (window) {
					var doc;
					try{
						doc = window.document;
					} catch (e) {
						return true;
					}
					if(Telerik.Web.Browser.safari && !doc){
						return true;
					}
					return !doc.defaultView && !doc.parentWindow;
				}

The Edit Content and other toolbar buttons are untouchable on Android Chrome on Galaxy S7, S8 and Note 5.

It is very hard to switch to edit mode and so on.

There is a bug in the editor when using the image manager to insert an image after creating a new image.  This is recreated on the live demo site - http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx

1. Open the image manager in the editor.
2. Click on an image editor after selecting an image.
3. Use the resizing tool to resize and save a new version of the image. 
4. Once the save is made, both images (the original and the newly created) are selected and when you click insert, both images will be inserted.

Steps to reproduce:
1. go to demo url http://demos.telerik.com/aspnet-ajax/editor/examples/edittemplate/defaultcs.aspx
2. click add new record
3. try to manually resize editor. it won't.
4. click add new record again.
5  try to manually resize editor, now it will.

The following concerns the editing of tables within RadEditor using the out-of-the-box Delete Row and Delete Column commands:
Delete Rows:
- Click in a cell.
- Click the Delete Row button. The row is deleted.
- The Delete Row button is still enabled, but when I click it nothing happens. The cursor is in the expected location and I'm able to immediately begin typing. However, I must again click in the cell for the Delete Row button to work.

Delete Columns:
- Click in a cell.
- Click the Delete Column button. The column is deleted.
- The Delete Column button is disabled. If I begin typing or click in the table it becomes enabled and functional again.

The end-user should be able to repeatedly click either button and have it work until there aren't any more rows or columns left to delete.
