I am running Lookout V6.6 on an HP desktop computer with Windows 7 64-bit OS. Lookout is running in XP mode. We are experiencing increasing frequency of the Lookout application locking-up. Yes, not much of a SCADA system when this happens. The OS System Manager shows Lookout "Not responding" and I have to reboot the computer before Lookout will operate again.
This is a simple SCADA system controlling two well sites with lead and lag pumps at both sites. It seems that lockups may occur more frequently when two pumps are being turned off near simultaneously. The computer uses a serial connection to a Zetron Controller talking to two Zetron RTU's in the field.
