Since I've installed Panther on my dual 1 Ghz G4 I cannot use Stuffit Expander. Everytime I try to use it, it says "Sorry, Expander requires Stuffit Engine 8.0.0 or later. Please reinstall from the original installer." I have reinstalled from the Panther disc and that hasn't helped. I don't have any trouble with this on my 17" iMac 1.25 Ghz running Panther. Any ideas?
