Ok, I'd been following the threads about that "virus" that can infect OS X if you download it and double click on it. The prevailing advice was to create a new account which would be the admin. account, and switch the regular account to a non admin. account. So I did that. Then, I seemed to have lost write priviledges on two of my three internal hard drives. When I clicked "Get Info" for them, the 'Ownership and Permissions' drop down menu was greyed out. And for a while, when I would try to copy a file to either of the hard drives, I got prompted for my admin password. So then I switched my main account back to an admin. account and was still getting prompted for the password. Now suddenly, the two hard drives still have the 'Ownership and Permissions' drop down menu greyed out, but I can copy files to either hard drive w/out getting prompted for the password. Anyone got any ideas about this? Seems pretty weird to me. I tried repairing permissions, but nothing changed. I don't understand why I still can't use that drop down menu. BTW, I'm using Panther 10.3.9.
