Cannot Exit Message, Access 2007

Tech-Archive recommends: Fix windows errors by optimizing your registry

I'm not sure where to post this, so I picked the umbrella database group which seems to deal more with basic technology issues rather than internal application glitches.

I have a user of a very simple Access database that has been running smoothly under 2003 for several years. Her workstation has been upgraded to 2007 and she is now getting the message "Microsoft Access has encountered a problem and cannot exit. We are sorry for the inconvenience... etc."

I have Googled this message and searched these newsgroups and can find nothing on this problem, and I have never seen it before. I have placed the network folder in which the mdb file resides in the Trusted Locations list in the Trust Center. The machine is running XP with all service packs current.

Thanks in advance for any help.
