By far the most common one is that your application is leaking window handles, induced by removing controls from their container with Controls.Clear() or Controls.Remove() and not disposing the control. That's a permanent leak, Windows pulls the plug after the process has consumed 10,000 window handles. Diagnose that with Taskmgr.exe, Processes tab. View + Select columns and tick USER Objects. A steady increase in this value spells trouble. The second one is much less common, induced by creating a window of a type for which the native DLL that implements the window class is not properly loaded or initialized. You'd have to use the CreateParams.ClassName property. The exception is instantaneous. share|improve this answer answered Jan 28 '12 at 17:23 Hans Passant 653k819581603 add a comment| up vote 1 down vote Try reinstalling your .net framework, but I'm not entirely certain this will work, since I'm not sure what the problem is that you're having. Yeah, I know it applies to 2.0, but it should also work on 3.5. If not, just go to add/remove programs and repair it there. sh
