Just discovered you guys while frantically looking for a solution to my newest problem. I recently updated to OS 8.6 on my old G3, then tried to install Navigator 6.2, which is supposed to be compatible. Can‘t complete installation because I keep crashing with error 1003. I also crash every time I try to join a Mac user group at the Apple site. If you have a tip, please be specific. I‘m a novice at this stuff!
