Whenever I hook my laptop (Powerbook G4) to my cinema display, my mouse arrow mysteriously dissapears. I have to use the keyboard to log into my system then once its logged in the mouse arrow returns. Any suggestions??
HAve you tried movingthe mouse during the login screen? I know that sometimes the mouse disappears until it's moved. It also disappears when you type so it's not in the way. This option is also resident in Windows and Linux desktop environments.
