Probably MFC tries to delete your CFrameWnd on application exit, but you have allocated it on the stack. MFC expects that frame windows are 'automatically allocated' by the framework, as they are when you use the 'normal' MDI/SDI approach with the wizards. They get automatically deleted when the application shuts down. Therefore, if you create a CFrameWnd manually, you have to allocate it via new and must not delete it on application exit. The framework does this for you... This is one of the more obscure "features" of MFC, for which I never found any documentation... Hope this helps, Nick EDIT: some typos
