I too installed this under a fresh install of Tiger with only stuffIt installed and all $#!! broke loose! I wish I had read this thread earlier. I'll try the uninstall options listed and see how that does. I did visit Griffin's web site and see there is NOTHING there pointing to any trouble which REALLY upsets me and makes me question if I will EVER buy anything from them again. I don't mind software compatibilty issues, they happen, I can wait for an update, but I do care when a vendor hides an issue and puts me through a weekend of hell trying to figure out what's wrong. I won't forget this Griffin!
