silverlight crash using sketchflow

[Arnold Schwarzenegger]

I am using Blend 4 beta and the free trial version (2010.1 309 (Mar 9, 2010) ) of the Silverlight RadControls.

When I use the filter tool in the column header, Silverlight Crashes and produces the error text below. Can you tell me what is going wrong?
