Man, I knew I was testing fate when I decided to upgrade from a 110% perfectly running Tiger OS to the new Leopard, but I did it anyway because I wanted the current version. Anyway, upgraded to Leopard and now have a problem: My admin account runs fine (aside from a lot of slowdown here and there, oh, and some lock-ups...sigh), but I created a second account....a Guest account....and that is where the issues are. The second account is normal in all regards, except I don't let that account access the admin account. It's virtually the same. The problem is, Safari and FF won't connect to the wireless internet via Verizon FIOS. Now, my admin acct works fine, but this new account won't. Any ideas? Also, are all you other Leopord users experiencing a lot of lag on programs (word, excel, disk utility, etc) and a lot of beachball lockups? I had to hard reset 3 times last night! Thanks fyi: MBP 17", 2.4, 4GB ram, 250GB HD (only 75GB used).
