I have a client who is getting this error on the PO screen, today I asked him to go to the SL location and run the 0425000.exe and he reported that he was getting an error when doing attempting to run the executable "another program is using this file". He was not running process manager on this workstation. He is not aware of any backup program running but they are typically seeing this in the afternoon, leads me to believe that something is running and it is always lock this same file. Any thoughts?
