I recently upgraded from 5.2 to 5.5 MR3 and I am now occasionally getting the error "OPS TP.CPP (1005) Unexpected DB Error, Call Failed" when we try and pick up a check. Touch ok on the error and it wipes out the check and changed the Guest Count to 0. We are using WS5A's. I have never seen it when using OPS on the server so I am thinking it has something to do with the workstations. Any thoughts?
