Hi Sheetal,
You may have a UIR that doesn't get closed or disposed of properly. Make sure DiscardPanel is called for every panel you load, as well as QuitUserInterface if you called RunUserInterface. Also, I would make sure any other memory allocation that was explicitly called gets disposed of properly (i.e. freeing any tied up memory) and any dlls you call properly clean up after themselves. It's possible that a DLL may be trying to access unauthorized memory space and cleaning that up causes a GPF. If these suggestions don't help, can you provide some more information about your application so we can try to narrow down the cause? Thanks for your patience!
