[AccessD] Lost error handling

My error handling routines have just stopped working. I first noticed it in 
Outlook and now Access is doing it -- VBA simply ignores my On Error 
statements and of course, the internal error handling takes over.

Anybody ever seen this?

I have trouble ever since I installed 2007 on the same system with 2003 --  
it's been one problem after another. Outlook still doesn't work properly. I 
uninstalled 2003, installed 2007, same issues -- can't create new mail or 
tasks. Oddest thing I've ever seen and I have no clue what's going on. I 
completely uninstalled 2003 and started over, didn't make any difference, 
same problem.
