I had the occasional crash with Safari while running Panther, but now that I've upgraded to Tiger, the probably has increased ten-fold. Safari is basically useless when there are tabs open. If I try to close one, it will crash. If I have multiple tabs open and I click a hyperlink, it will crash. When I quit the program, it will crash. I tried all the troubleshooting suggestions in the Apple Support forums, but nothing is seeming to help alleviate the problem. I did create a second user account, and it didn't seem to have any problems, so I'm suspecting I have some sort of file somewhere that's causing Safari to run strangely. Like I said, however, I tried everything suggested in the support forum, with no luck. Any thoughts? Anyone else having any troubles since upgrading to Tiger? I'm running a 1.25ghz 15" G4 Aluminum Powerbook.
