No, it is not the same issue as that.  Quick Fields closes but it still shows as an active task in Task Manager so the next person logging in cannot because the "number of users has been exceeded."

Are you running QF from a standalone machine or Citrix or a VM?

Our laserfiche server is a VM, QF is running on that.  People log into with RD and then run their QF, close it out and then exit out of RD.  But when QF closes, sometimes it hangs in the task manager.

You noted that you have people login with remote desktop then close out of QF and exit out of remote desktop.  When they end their session, do they close QF then logout of remote desktop or do they just hit the x in the RDP session to close out of it? 

If they do not close QF properly and close the remote destop by simply hitting the x to end the rdp session, then QF would not be terminating or closing the session. It will remain running for the original session and you would have to end the QF task.

Also, you would get the "maximum number of users" or sessions message when two or more users are trying to run QF at the same time which would not be allowed.

They are closing out of QF and then closing out of RD.  These people typically run QF at different times during the day (designed that way for this reason).  Our problem arises when QF is closed but does not end the task itself.
