The hint works except with at least two different VNC clients (Chicken of the VNC, Jollyfast VNC) and two different servers (OS X Screen Sharing, Vine Server) the mouse pointer does not show on the remote though clicks and drags register on the remote. Without the pointer the hint is not useful. Client is on a 10.4 Mac, host is on a Mac is a 10.5 mac.

I noticed this too and indeed if you use those VNC apps the hint is not very useful. I'd suggest using Apple's built in VNC as I find it to be quite fast, invokable from "Connect to Servers" in the Finder (eg vnc://machine.local), and I generally like to use built-ins when I can. Give it a shot...

Sorry for duplicate post, but I wanted to keep the thread. I don't believe that is an option with a 10.4 client.
