Ever since I installed Snow Leopard, every so often when I try opening System Preferences, it just keeps bouncing and never opens and says it's not responding. If I force quit and reopen, it'll suddenly open on first bounce. This happened on 10.6.0 and 10.6.1. For context, I installed SL clean on my iMac Core Duo. The only 3rd party apps in System Prefs is Backblaze, Flip4Mac, GeekTool, Growl, iStat Menus, and Perian. All are up to date. I thought it might have something to do with some sort of 64bit/32bit conflict, but since my iMac is only 32bit anyways, wouldn't think that would be the problem.
