Ending A "Orphaned" Program

I have a user running Windows 7 Professional 64-bit and the current version
of i Access. Twice last week at the end of the working day this users PC
locked up and the user just turned it off and went home. Unfortunately, the
user had opened our shipping program which is a green screen program that
opens many files including our order files. At 9 PM we run our end of day
processes.

All users are off the system no later then 5:30 PM. Anyone who leaves their
device at a menu, etc., gets signed off by the system after 2 hours so the
nightly processing is not impacted. Not so with this issue. It will sit in
QINTER until we kill the job manually. Unfortunately it really screws up
the nightly process. Looking at the job log I see a CPF5140 followed by a
CPF5503, both are dianostic messages.

Will either of these messages cause a MONITOR loop or the *PSSR error
subroutine to trip so I can cancel the program? I plan to do some testing
of this but I suspect since they are diagnostic messages they may not. Is
there another way to interrupt the program and attempt to end it if this
happens? Perhaps just ending QINTER prior to nightly processing resolves
this issue.

Thanks all.
