Usanity says that cleardock is compatible with Panther. But Now I'm having the same problem on my iBook G3. The dock dissapeared and won't come back. Quite annoying. I did everything. (restart, permissions, unistall, reinstal, etc)
Another thing about the G3. Exposé won't work. When I select Window mode for a corner, it just won't stick. It goes back to "-"
Wierd...
Did anyone make it work on a G3 iBook ?
