Application Termination Problem in Windows XP

Hi,
I'm new to Windows XP and it seems that my app is not terminating properly because I still see it in the Task Manager after closing it out. I've debugged through the code and put breakpoints in the destructors and everything is being destroyed properly and it DOES terminate properly only when I am in Debug mode in Visual C++. But when I just close out the application (not in debug) it is still running somehow. Is anyone else having these kind of problems? Is there a patch for XP or visual, or is it really a problem with my application (which always closed properly in Windows NT)? Thanks for any help!

post your wndproc.
if mfc then wrap it up in a zip and post it.

never mind....i found the culprit.
The shortcut for the application was changed by someone to Run on compatibility mode for Windows 98/ME, i unchecked this and now it terminates properly.
