Great! Thanks! At the moment everything is working again :-) By the way: It was not my internet connection, because I have 16 Mbit/s down and 1 Mbit/s up, and this also happens at work ( 6 MBit/s). So it was the peak time and/or the big categories (like c#). Regards, Sascha

I want to repaint/refresh Windows Mobile! And not my own application, because my own application isn't shown on the screen. If I draw directly on the screen above EVERYTHING, I want to delete this after closing my app. So I have to inform Windows Mobile that it has to repaint EVERTHING displayed on the screen.
