Doug: Thanks for the information. I have had a lot of issues of *FROZEN* systems (currently 10.4.11). I was all over the place in guessing what is causing it. I thought I had it narrowed down to Safari and the RSS feed. I turn RSS feed to no and I still get the freezes but not as often as before when II had RSS feeds turned on. I have a Radeon 9650 (I do like it).
