Something changed in MFC in VC7.0

[Mukkie]

Hi! I recently ported several my projects from VC6 to VC7. I have noticed large memory leaks. After some debugging, I have found out that ExitInstance is not called any more. This is due to fact, that window is destroyed far more earlier (I think) than before. Application exits (quits ,immediately) in CFrameWnd::OnClose() during DestroyWindow() - last line in this method. What is the reason? I cannot find any document which describes this issue. :confused:
