Prof UIS keeps crashing. It all seems to have to deal with CPaint destructor. Below is a snippet of code that appears in the debugger when the crashe occurs. There is not specific entry point or sequence when the application crashes. The crash occurs randomly crashes.. When the crash occurs CExtButton, CExtStatusControlBar, CExtToolControlBar, or CExtControlBar will appear in the debugger. But the lines listed below always seem to show up. The crash always ends up showing CDC::Detach() Line 122 and CHandleMap::RemoveHandle in the debugger. Can anyone suggest how to fix this or a likely cause. GDI Plus was introduced in the application and the crash started occurring about two weeks late. I can not see how using GDI Plus would cause this crash since the crash seems to originate in CExtButton, CExtStatusControlBar, CExtToolControlBar, or CextControlBar class.
