This is a resend, pardon if it went already; I got no copy so I suspect it never went.

Thanks for your reply.

There is no real code involved in the issue.  My main form, fMain, has a subform, fStudent.  When the user picks a student from a drop-down list on fMain, fMain sends the subform fStudent the id of the selected student.  Upon receiving the student id, the subform makes that student record the record displayed for editing by using the code 'Me.RecordsetClone.FindFirst "student_id = " & cstr(id)' followed by (if no error) 'Me.Bookmark = Me.RecordsetClone.Bookmark'

This part works as desired.  I have stepped through the problem and found that this code is not run when the problem occurs, thus is not causing the subform to move unexpectedly to the undesired record.

 If the user then chooses to edit the (tabbed control displayed) student data by using the Windows operating system functions ctrl-c, ctrl-v or ctrl-x, the form unexpectedly jumps to a new record before the ctrl-? function acts, and the action is then applied to the new, unexpected record!

As for when it started happening, that is unclear, but probably not too long ago.  At first the users thought they were making a mistake, that they were in error somehow, and didn't bring it to my attention until yesterday.

Clearly I need to find out if something was changed in the recent past: upgrade to server, or to workstations (tech support has the habit of making changes without telling anyone).  One of the techs thinks that a Win XP Office 2002 - Office 2007 compatibility upgrade was done recently on the workstations, so I will pursue that as well as whatever else I or others can think of.

Thank you for considering my problem.

Fred

Hello,

It's hard to understand your problem. When did your problem appear? Show 
us your ODBC + PostgreSQL relative code.
