MSN adCenter Not Compatible with IE

Just a quick note that I saw on adCenter blog the other day about the compatibilty of MSN adCenter and different browsers. Like most Microsoft products, it is not compatible with Firefox but that comes as no surprise. What I do find funny is that MSN adCenter does not work with IE7. IE7 is still in beta and I'm sure this issue will be fixed but you'd think there would be a little better inter-office communications by the Redmonians.
