Do you know of any issues, off the top of your head, with testing IE7 or FF3.x or Safari or Opera -- any heavy hitter items to be aware of that may crash a UI based content management system application?
The accessibility testing, as I've researched, will take care of itself.
I've done website testing for a map site in IE/FF, etc. and the "known issues" were things like back/fwd buttons & printing. I was just curious if there's anyone out there who may know of more "heavy hitter" type items to look for when testing in UI/browsers.
