If we close Sys Mon on our Engineering box (P91) and the operators open it on ether of their boxes (P91 & P92) we cannot reopen Sys Mon even if we close it on their boxes. If I remember this right we have to reboot our boxes to get it back. Why does this happen? Our Eng box is the main server for our thin clients and runs the Aim* historian. Also I thought that Sys Mon could only run on instance at a time on our system. But the operators can open it after we have opened ours, so it can run on all three boxes at once. I don't think this is the way this should work...but then again I don't understand everything I know about this system.
