Installed Leopard last night & now Safari mysteriously closes the browser window. It leaves the menu bar at the top, but I still can't open a browser window. I have to restart the mac to get Safari to work again. In a matter of minutes, Safari closes again. I've seen a few discussions of similar problems, but haven't found a solution that works. Anyone else had this problem.....and hopefully found a fix. Other than waiting for 3.0.5. Thanks in advance!
