Well, I'll go so far and say we had an app here that was made for Acc2000 which would blow up when opened under 2007, and it didn't after adding sp2.
I haven't fully tested the app to see if it will behave, but it *seems* to have made a difference at least in so far the app doesn't auto crash anymore.
I looked for the screen shot that the end user sent me, but I must have deleted the email. (That user drives me crazy so I am not surprised, but I wished I could be more helpful here).
Good luck.
