I have an application that should close when the OS is rebooted or whatever.

I have "on shutdown do THE ONLY QUIT" (source below) set and generally it works when I logout, reboot or shutdown - sometimes, particularly when the application is minimized, the application will throw a "Fatal Exception code=C0000005" pointing at the "read events" command somewhere in the top of my "main.prg".

PROCEDURE THEONLYQUIT
*------------------------------------------

on shutdown QUIT && prevent recursive calls

*...
* some other cleanup
*...

close databases all
clear events
QUIT

RETURN && ---------------------------------

Any ideas ?
