When the command dialogs from two ImageEditors on a page are opened consecutively, the second dock is rendered with wrong position. The issue most probably comes from the fact the second dock element (ToolsPanel) is appended to its parent ImageEditor, but not to the form.

Assuring that each dock is appended to the form element can be used as a temporary workaround of the issue:

        <telerik:RadImageEditor ID="RadImageEditor1" runat="server" Width="680" Height="450" OnClientDialogLoaded="ClientDialogLoaded"
            ImageUrl="waterpool.jpg">
        </telerik:RadImageEditor>
        <telerik:RadImageEditor ID="RadImageEditor2" runat="server" Width="680" Height="450" OnClientDialogLoaded="ClientDialogLoaded"
            ImageUrl="waterpool.jpg">
        </telerik:RadImageEditor>
        <script>
            function ClientDialogLoaded(imageEditor, args) {
                setTimeout(function () {
                    $telerik.$("#<%=form1.ClientID %>").append($get(imageEditor.get_id() + "_ToolsPanel"));
                }, 0);
            }
        </script>

A large uploaded image is not saved properly after cropping in disabled CanvasMode. Instead of saving the cropped part of the image, the control is saving the original image resized to fit the cropped part size.

The issue is reproducible both by using the Save dialog (Save image on server) or the saveImageOnServer() method.

Steps to reproduce:

1. Open http://demos.telerik.com/aspnet-ajax/imageeditor/examples/imageupload/defaultcs.aspx in IE8
2. Upload the attached image
3. Crop a part of it
4. Save the image on server

Result: The original image is resized with the crop-box dimensions.

The new version allows shape resizing on the image editor. 

However this is not working in a stable fashion. Here is the list of steps to replicate

a. Draw a rectangle
b. Hold the central marker to drag the rectangle. it moves slightly and then nothing happens
c. Try holding any other marker to move the rectangle it does not work

After the LIB (2013.1.423) the Save (on server) functionality of the ImageEditor doesn't work properly and throws a javascript error.

When a big image(~3MB) is loaded into the ImageEditor ( with enabled CanvasMode) sometimes the image is not loaded into the controls or the whole page crashes. The issue could be reproduced in Google Chrome, with the 2013 Q1 SP1 version of the controls.

When the CanvasMode of the ImageEditor is enabled, the JPG images are saved as PNG.

Steps to reproduce:

1. Open the following online demo: http://demos.telerik.com/aspnet-ajax/imageeditor/examples/canvassupport/defaultcs.aspx

2. Use the configurator above the ImageEditor to enable the CanvasMode

3. Save the image, choosing the "Download image" option

4. The image, which original format is JPG is saved as a PNG (with increased size)
