But what if zip files are assoziated with a StuffIt application? How do you get Panther to open zip files instead of Stuffit? Easy: Get Info on the file and select this application: /System -> Library -> CoreServices -> BOMArchiveHelper.
[robg adds: You can/should also check the "Change all" box so that all zip files gain this association. I haven't had any zip issues, but I did clean installs ... but maybe I've just been lucky so far.]
