It doesn't have less functionality, it definitely has more. It takes a little while to get used to it, and i sometimes wish it was possible to make the navigation bar along the top narrower, but i really like it, i has some great new functions.

Rachel , you might be able to advise me in that case.
When I use conditional formatting in '07, I only get the option to conditionally format three rules at a time. Is there a way of increasing the number of rules you can format in a single column/row? I regularly have a need to format results for up to half a dozen sets of information in a single column....
