Hi. Thanks for your reply.

Strange, I'm also using Silverlight 4.0.60310.0.

The errors have been there since I started looking at ClientUI several months ago, before the current version you have out.

Some of the errors aren't always there. E.g. right now, I opened live.clientui.com and selected the "launch sample" from the cover flow control. The new grid view samples opened without problems. From there, if I press the "Browse all" and then Grid View, I get the same "Exception has been thrown by the target of an invocation". The treeview, on the other hand, always crashes.

I've tried to empty IE cache and the Silverlight app storage, but it doesn't help.

You can call me (+47 / 97794414 between 9 and 19 CET) if you're interested in looking at the error through a web collaboration tool.

Thx
Tor
