Switch to Access 2010

[NISMOJim]

Hello Access Geniuses,

My office is about to change over from Windows XP & Office 2007 to Windows 7, Office 2010. Most of my databases were written in Access 2007, a few were written in 2003 & converted to 2007. I've heard a few things about Macros not working, but what kind of problems can I really expect to run into with this switch?

Thanks for the advanced warning!

I don't use macros, only VBA. My experience running older dbs with 2010 has been without issues.
