Also, if I try and eject a network drive because it isn't reachable (such as the other machine has been shut down, or I've turned off my wifi), then the whole machine crashes, and it's the same for everyone else I know who's on Tiger.
If you're patient it does timeout after a while. I do agree the network stuff is a bit rubbish, but it is under Windows too, so Apple doesn't fix it (or maybe it's just very difficult to fix).
Anyway FTFF (Fix the ******* Finder) for Leopard is what I'm hoping for.
