VFP8 SP1 application because VFP9 will not be RTM before the project is due.

I have started a new project the uses a top level form and the rest of the forms are shown in the top level form. The Desktop property is false, and the ShowWindow property is set appropriately. I am having a problem getting the EXE from releasing from memory when I shutdown the app. I have been quite thoughtful about garbage collection and releasing objects I created, but obviously I have missed something. Now the $64k question, does anyone have any tips for how to debug this? Once you run the app, the debugger is useless, and if I try to dummy-down the app by running in the desktop, the conditions are changed. TIA!
