WinForms controls are flickering when resizing on Windows7 x64

Question

This very strange.

When I resize a WinForms dialog the controls are flickering very bad, some of them are disappearing. It happens only when using the application under Windows 7 64.

Double buffering is disabled in Windows Forms by default, and unfortunately you get this flickering issue as a result. It's a pain, but that's the way that it is. You may want to read the following, or provide some more information about your situation if these do not solve the problem.
