Drag and drop from Visual Studio Toolbox to the designer area doesn't allow you to drop the corresponding control inside the content of the selected tab item. 

To work this around, add a Grid panel with transparent background inside the RadTabItem's in XAML. You can do this also  through the toolbox.

 <telerik:RadTabItem x:Name="RadTabItem1" Header="Tab item 1">
	<Grid Background="Transparent" />
 </telerik:RadTabItem>

Note, that the Dispose method of the RadMap needs to be called in the Closed event of the Window in order for the exception to occur.

If you have an XML attribute with a string value, but the value is not fully rendered into the viewport, its color defaults to black, instead of the expected blue color.

To work this around, you can create a custom XmlTagger and override its GetTags() method. This will allow you to properly catch the string value and return it as a tag span element with its ClassificationType set to "string".

StackOverflowException is sometimes thrown while a document containing annotations is updated in the main thread (e.g. by typing in it), and spell checking is enabled.

The exception is thrown in a background thread, which call stack similar to this one:

The ImagesDeflaterCompressionLevel and ContentsDeflaterCompressionLevel in the PdfFormatProvider's export settings have 0 for default value instead of -1.

Workaround: Change the settings's properties to -1 explicitly.
