We've been having trouble with OPOS when running RMS POS under one of our AD Power User or User accounts. On certain POS terminals, we have no trouble running it with a standard user account but the rest all need to be logged in as an Administrator for it to work properly.
It never gives out a specific error message and there's no mention of errors in the Event Logs, but instead it will do strange things like print a copy of the previous debit/credit transaction off instead of the current one. For example, Trans #1's debit slip will print fine. Then when Trans #2 completes, only the slip from #1 will print off. On Trans #3, #2's slip will print off, etc etc etc. We've also had some trouble with occaisionally double billing customers and with our day's end reports but I haven't been able to reliably reproduce them, nor tie them directly to the Admin Rights issue.
I came in after all of these were set up and the last SysAdmin didn't leave me any documentation so I don't know what he/she did to set any of it up.
Any ideas? Should I just uninstall/reinstall and see what that does?
