Vikki, My Sawtooth did work again after I fiddled around a little. Appears Firewalk X doesn't quite work right with Panther. Everything else works great though. Shouldn't cause a problem for you. As for whether to upgrade or clean install, I would recommend an upgrade, but back up first. When you select the destination volume in the installer click the options button and select "Archive and Install". That will archive all the 10.1.5 stuff to another folder on your hard drive. Just to be safe, I'd back up though. CJ
