Currently, it is possible to align an image using the Justify Tools of RadEditor in IE, Chrome, Safari and Opera, but not in Firefox. In addition the content produced in the different browsers is different.

When dragging items from an outside source into a RadEditor, be it text, image, video, etc. The API used to perform drag & drop is lacking. For example, an overlay needs to be shown over the top of the iframe element for the editor, whereas I would like to perform the drop at a specified area where I drop - not where the cursor is located.

Whe you're trying to add an image with "#" or "&" symbols in it's title - image displays as corrupted in image editor.

After editing the properties of a hyperlink in Chrome the link just disappears. See the video at http://screenr.com/XxX7 which demonstrates the issue occurring on the demo site.

When a user is trying to insert new text inside other's user not accepted change the cursor is automatically jumping in the end of the unaccepted change. Different expected behavior can be the change to break the current change.

If a RadEditor is placed in an UpdatePanel and it is initially invisible (its property 'Visible' is set to false), the skins of the dialogs will not be loaded correctly when the editor is displayed ('Visible' is set to true).

In RadEditor, when creating a table, then going to the Table Properties/Style builder/Border option, the Border Width information is pushed down and not all options are accessible.

Inserting a new link or inserting a link over selection from Hyperlink Manager is not possible in Internet Explorer 7

FIX: RadEditor in an iframe on iPad grows infinitely

The following workaround could be used temporarily:
   <script type="text/javascript">
            Sys.Application.add_load(function () {
                var editor = $find("<%=RadEditor1.ClientID%>");
                var viewportWidth = document.documentElement.clientWidth;
                var viewportHeight = document.documentElement.clientHeight;
                editor.setSize(viewportWidth.toString(), viewportHeight.toString());
                    }
        )
        </script>

When a document is deleted from the DocumentManager, its selection remains and it could be inserted into the Editor.

Currently when pasting an ordered list from MS Word, the RadEditor’s lists converter does not take into account the list’s items numbering. 

The following list
 
5.	Li1
6.	Li2

will be converted to

1.	Li1
2.	Li2

Create a page as below and assign a limited toolset to each editor in the code behind:


 <telerik:RadEditor  ID="RadEditor1" Skin="Default"  ContentAreaMode="Div"   runat="server"      Width="265px" Height="120px"  ToolsWidth="265px">
       <Content><p>A Word</p> </Content>
</telerik:RadEditor>
        
 <telerik:RadEditor  ID="RadEditor2" Skin="Default"  ContentAreaMode="Div"   runat="server"     Width="265px" Height="120px"  ToolsWidth="265px">
       <Content><p>A Word</p> </Content>
</telerik:RadEditor>
        
[Continue with this until ...]

 <telerik:RadEditor  ID="RadEditor10" Skin="Default"  ContentAreaMode="Div"   runat="server"     Width="265px" Height="120px"  ToolsWidth="265px">
       <Content><p>A Word</p> </Content>
</telerik:RadEditor>
        
Now display this page and right click for the top editor's Context Sensitive popup menu. Now scroll down to the bottom menu and right click for that menu's context sensitive menu. My experience is that this will erroneously produce the popup at the top of the browser. This is the most extreme example of a general behaviour where the vertical placement of popups is typically off the mark when working with multiple editors and ContentAreaMode="Div". Get rid of the ContentAreaMode="Div" and the problem disappears. 

If change the font in the middle of a line and start typing the new font is applied .

However when translated to a new line, the font reverts back. 

When the Template Manager tool of RadEditor is enabled, the content of its dialog window is not loaded under IE.

1. Go to http:/demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx
2. Choose the bullet list command from the toolbar and type some text
3. Choose the FormatCodeBlock command and insert some text
4. Press SHIFT+ENTER to insert <br>

Actual: If you continue pressing enter, new lines will not be inserted.
Expected: New lines are inserted.

I have problem with "Strip CSS formatting" command in Chrome, for example this html as editor content

<span class="redText">test test</span>

In Firefox when I select this two words and select "Strip CSS formatting" it works with no problems, but in Chrome text stays the same, I managed to reproduce this issue on your demo page http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx
