- Fix a problem where application that used WH_CBT hook procedures were receiving destroy window notification on windows that were never created. The window was never created because the application had returned a non zero value when it was notified of window creation, which effectively destroys the window and returns failure for window creation. See CBTProc Function on MSDN. Fixes bug #4461.
