Despite our efforts, we also did not manage to reproduce the described issue. I am attaching a movie which demonstrates the behavior on our side with Windows 7 OS and RadControls for WinForms Q3 2010 SP1 (v2010.3.10.1215). The project that you see on the movie is also attached.
Please open a new support ticket with a sample project which demonstrates the described behavior. In addition, please provide us with details about the DPI and screen resolution settings.
