I have a G5 with 2 log-on accounts. My friend's log-on works fine and he uses Safari, but mine suddenly opens, closes/opens/closes in a repeated loop. If I can get the "Try again" window to come up, sometimes that fixes the problem temporarily, but when I shut down and re-start again it starts that loop. It's right when the desktop loads. I see it for a few seconds then everything disappears and I get the "Safari suddenly closed" message and then the loop starts. Any ideas I might try? Thanks, Mark
