Ha, mac, I get so tired of scrolling that even if it is fast I can't tell couse it seems to go on forever! It seems slow on mine too, but it's not really too bad yet - is your runtime over full? That can slow down the library files, I've heard. obm, thanks for the mouse info - I upgraded drivers not very long ago, but will try again, maybe that will do the trick. Do you ever wonder if the people who design the interface have ever actually used Poser? ;D
