I'm a graphic designer. I have 8000 fonts on my Mac. This is the year 2010. Would someone from the Microsoft Mac Business Unit please explain to me why Mac Office has to spend 10 minutes going through all of my fonts before the app launches. No other Mac app has to do that and it's the same in Office 2011 Beta 5.
