Ah - didn't really work.
Some icons in Win7 remain tiny, so small they're unusable.
Main issue is my mouse - the speed is now hugely different to when I'm in OSx - in Win 7 my mouse now needs to be pushed over 2-3 times as far to move across the screen. And I can't move it to the top of the screen (ie in the the OSx top section). This makes is unusable.
Come on VM Ware - make a proper fix otherwise this is a showstopper and I'll go to Parallels.
