I have a Bluetooth mouse that I use with my MacBook Pro. In Tiger & Leopard, I was able to set my Mac so that it disabled the trackpad from use when the Bluetooth mouse was connected. I just noticed that that setting has been undone and I can't seem to find the preference to set that setting. Anything? Thoughts? This obviously isn't a crisis, I'm just curious if they've moved the preference someplace else... or something.
