Hi Bill
big thankyou for reply based on heaps more experience than I have.
And for taking the time out .
I did try compacting the database but this didn't solve the problem (on either machine).
I can't make it happen with two new forms open concurrently - must admit like most I'm tied to
deadlines and just want it to work....
As you rightly point out, my assessment of Access 2010 and 2013 really isn't worth a candle.
Words born out of frustration. The better you know any apps development medium, the more you instinctively go with the strengths and work around the parts that need it.
I resorted to back to backups and rebuilt the database - full steam ahead now.
Thankyou again
Jerry
