Hi telerik
I'm using RadControls for Silverlight 2011.3.1116.1040.
When use RadBook control with a New RadDocument as Source, it throws UnHandledException and can't close ErrorMessage so I can only refresh browser.
I send this demo project to reproduce this exception.
You can reproduce by click in Radbook's top-right conner and drag it to middle like you're flipping page. It'll show continuously ErrorMessage.
Can you resolve this bug in next internal build?
