In my opinion focus follow mouse is still not quite ready for prime time... in other words, I don't use it.

As far as the performance boost check box. KC told me what it does... I told him to name it something else because he was going to get questions about it. Here is my chance to say "Rob, I told you so."

but I am not going to say that because I forget what he told me... If I missremember correctly it was something that someone playing a game other than wow requested and thus... since it had nothing to do with wow I immediately forgot about it.
