The mystery is solved!

As it turns out, I will not need to kill any running executables. I had been running a form- hidden- and doing the processing in the form's
ACTIVATE() event. I was not, however, UNLOADing the form, so the form object was still in memory, and thus the process was still running.
I have moved the code to the form's LOAD() event, added an UNLOAD
[form name] command, and then END. Now the app runs and closes properly, leaving no processes running.

Thanks for your help! I'll keep the code handy for the future.
