I have two user controls that contain the telerik radwindow.

When I try to open second window on first window button click, I get the below exception:

Hmm i have occassionally experienced this also, and the best i have been able to tell it is related to a mouse event, and it appears to originate solely from within the telerik component, but i have never been able to replicate it. – slugster
