Hi Ahmed,

Thank you for the provided stack trace.

Could you please, however, specify whether this issue is present with any of the demos available in the WPF Controls Samples application? Could you also specify the exact version of Windows 7 you're using and whether applying any of the updates specified in this forum thread works for you?

If you have an active Telerik license, you can also download the source code of the demos from your Telerik account as explained here. Do let me know if this would be possible for you.

I'm looking forward to your reply.

Regards,
Dilyan Traykov
