I beginning to think I'm going to downgrade, despite the speed.

I can no longer click on any of the formatting buttons within the "Compose Post" or "Reply to Thread" windows. Well, I can click on them, but nothing happens.

I've also lost the "Thread Tools" drop-down pick-list that is at the top of a thread when viewing it. While that one is probably not a huge one for most folks, it makes doing moderating housekeeping stuff much more difficult.
