Andrew we did that & it fixed it for a moment. Like minutes. The problem has been ongoing still. I just looked & we have OEF001 - OEF004 currently.
What now happens & I believe this was the case all the way along is the 1st person to open OE & looks up using the F6 as described by Barb gets this lock...If the same person opens a 2nd copy all works perfect. The problem can move from user to user when the OE function that is messed up is closed then the next in gets it. All other users are OK as soon as one locks the problenm to themselves.
