debug assertion failed

[Reevesi]

Hi I am returning to programming after some time doing other things. I took on some Visual C++ 2003 applications that were working. I made some changes and everything was OK. Then somehow I lost references to additional MySQL libraries and KeyLok2 libraries. I added these back and got clean compile and link. But now I get "debug assertion failures" in files like afxwin1.ini, wingdix.cpp and wingdi.cpp. This did not happen before. Does anyone have any idea what I need to do to get debugging again?

And I saw this movie where some guy tried a few things and I would like to know how to try those...

You need to be more specific than "It worked, now it dosn't" thats like guessing the speed of the moon depending on a butterfly's wing span.
