A critical problem holding up an upgrade:

Background: We've been getting ready to move from FP 2.6 to VFP on our accounting software (SBT).

This requires "bringing along" another large app with a Foundation Read. I've been directed to do "minimal" work on it (let's call it the MAIN program). I've found that simple windows get removed fine with RELEASE WINDOW window_name, but on Parent windows with Child windows, when I "RELEASE WINDOW window_name", no matter what I do, the window remains in memory, even after it has passed the RELEASE WINDOW point in the code. (Remember, when running Visual 5.0)

If I go to the Command Window, and type either RELEASE WINDOW window_name or CLEAR WINDOW window_name, the window is cleaned from memory, but it is not cleaned during running code.

Since the code logic (I didn't write it) branches on condition of existing windows, I have to find an API, I think, or some other active method of removing the Window information sitting in memory.

Thank you for your help.
