David,
The application framework I'm using does have code in the Activate and Deactivate methods. I'll look at it and try the other suggestions below and let you know what I find out.

Thanks for your input!

Ed

>>I appear to be having significant problems with VFP 5.0, Service Pack 3, having to do with the debugger. I can run my code and produce the expected results when I'm stepping through it with the debugger. However, I can run it without the debugger and find that some events (specifically InteractiveChange, Valid and LostFocus) do not appear to run. I say "do not appear" because it looks like the values are not what I expect in a text box as I run the application.

If MESSAGEBOX is in the method code, and I hit a button on a toolbar or menu item that saves the info in the form, the message box appears, the form on the screen appears current, and the record is saved. However, if I leave the MESSAGEBOX out and do the same test, the form doesn't reflect the record changes, nor does the saved record.
