The default jobq used by my profile is the same single threaded queue used by everybody else on our machine.
Needless to say, if I allow PTDVSERVER to run from there I'll liable to get nasty notes at the very least. :)
So before starting PTDV, I have to remember to hold the job queue, wait for PTDV to submit the PTDVSERVER job, move PTDVSERVER to another queue (usually QUSRNOMAX) and release our regular queue.
It'd be a lot easier if I could tell PTDV what queue to use.
