I pass all the info (HWND windows


The MFC framework does not always give you the *real* HWND to a window. As strange as this might sound, the MFC framework maintains two object maps. The 'real objects' and an internal 'temporary handle map'. MFC will sometimes give you a temporary CTempWnd instead. If you are passing the window handle of a MFC class then you need to use CWnd::GetSafeHwnd[^]. There are some rare occasions where GetSafeHwnd cannot give you the real window handle and will return NULL instead so you should probably check for that too.

Not many people are using MFC these days. You should consider moving on.

I can't think of much else that would cause WaitForMultipleObjects to throw an access violation. The only other thing I can think of... is a corrupt heap. Sounds like you are somehow passing garbage to WaitForMultipleObjects.
