  1. I hope it fixes whatever has been making Dictionary crash all the time. System Preferences crashes about every other I launch it, too. Really annoying. Has anyone else been having these issues with Snow Leopard?

  2. @spj:

    I’ve never had any crashing issues with Snow Leopard, nor have I heard of any widespread complaints. Would advise downloading the 10.6.3 combo updater from the Apple website and installing manually rather than relying on Software Update.

  3. @spj:

    Ditto with never having crashing issues with Snow Leopard, particularly with Dictionary and System Preferences. Could it be a font problem with Dictionary, and have you validated fonts with FontBook? (Just guessing.) The only thing I could imagine messing with System Preferences is a corrupted preferencepane, maybe a third-party one, though I’ve got several (FlipForMac WMV, Glimmer Blocker, Growl, Perian and SizzlingKeys) and I’ve still never had it crash on me.
