I discovered something tonight related to a Leopard bug that has been bugging me (no pun intended) since its release. Leopard's new dock is slow. It lags, drops frames, and feels sluggish overall compared to Tiger's simple dock. ...Except just now, when I discovered it can animate just as fast as Tiger's dock. Here's how I managed that: Download & Install Growl 1.1.3 beta 2 from here: http://growl.info/beta.html Launch Growl's Preference pane, and change the default style under 'Display Options' If your system is like mine, this will cause System Preferences to beachball. Enjoy your new, faster dock! As soon as I force quit the unresponsive System Preferences, my dock returns to normal. This is reproducible on my machine (a Mid-2007 Macbook Pro running 10.5.2 with the Graphics update released last night) even under a fresh user account, so I know it isn't a profile issue. Can any one of you with a quick eye try the steps above and reproduce my results?
