Late this morning on my iMac 24" with 10.6.2 it didn't matter whether I was using Safari or Foxfire the would both freeze and I get the maddening beach ball and have to force quit. Any ideas why this would suddenly start happening? I haven't done any thing special to the iMac as far as memory or anything. My laptop isn't doing it, just the iMac. If you have any suggestions let me know. Thanks
