Sometimes left over object references will keep a program running, even though you have executed the End statement. An alternative is using the ExitProcess API to close the program. What I did as a safety is to load a form (that is not visible) with a timer before using the 'End' statement. If the timer fires, use the ExitProcess API:

Public Declare Sub ExitProcess Lib "kernel32" (ByVal uExitCode As Long)
ExitProcess 0

>When I close my app, it appears to close, but if I pull up the ctl/alt/del task menu, it is still showing on the list. I am using the UNLOAD command to close the program. Any suggestions.
