Hello!
In rare cases dialog window looks like on the attached screenshots. This problem is observed on Windows XP only in rare cases. Typicaly this problem happens right after application is launched.
What can cause this problem? How it can be fixed?
I have tried to reproduce the issue, but with no luck. Attached you can find a video and a simple project where I have tried to reproduce it. I have seen that you are using a Vista theme, can you please tell me how do you set the theme? Also can you confirm that you are using a WPF 4.0 with 2012.1.326 version of the controls? It would be great If you can isolate the problem in a simple project and send it to us.
Kind regards,
Georgi
