I just got my 12" 1GHz iBook with 768MB RAM. I have noticed that the "waterfall" type of animation for sheets doesn't happen. In Safari if I hit command-S the saving sheet just appears, it doesn't slide out of the window menu. Does this mean that quartz extreme is not fully working on my iBook? I can do the Shift slow-mo Genie effect minimize. I have the stock 32MB video card.
