A2K on 2003 SR2 Record Lock Problem

I have insured that there is no one else is in the system. I rdp into the
system and pull up a record. I do nothing to the record and click on the
cmdClose button. I get the error that "another user has edited the record
copy to clip board or drop changes.

On open of the form I do some calculations and insert the results into a
total field but I would think the close would take care of the update without
this error?

Any help would be appreciated.
