I'm using Office 2003 and the other four developers in the office are using 2002. Does anyone know of any serious conflicts or compatability issues between these versions, or between 2003 and previous versions?

We're particularly concerned about the protection facilities in Excel, which were made much more versatile in 2002 enabling users to do a range of specific selectable things such as formatting and other useful options , since we use these extensively.

Any pointers would be much appreciated.
