Is Magic Trackpad recognised in Sys Prefs with gestures?

[imacken]

I'm running ML in PD7, and although the Magic Trackpad works in most senses, it is not recognised in Sys Prefs, and most gestures don't work.
Is it OK on a main install?

I installed it as an upgrade from Lion, and my magic trackpads work fine (I have one in my MBP, and also a bluetooth one) with all gestures. By default, it changed some of the 3 finger gestures to 4 finger ones; but it's easy enough to change it back.

Thanks. Can I ask one more question? Do Youtube videos play OK? I'm sure they do, but they don't in my install, although I'm assuming it's a VM thing.
