That wouldn't be a bad idea. I am happy to play with it, well its my job to, but I have no intention of using it for the time being. I have no intention of releasing it to the users at my work yet either. That said the machines at my work are no where near a good enough spec to use it properly anyway. Like I said earlier turning Aero glass of has solved a good few problems but then what's the point as its nothing special after that.
For anything that is giving you problems in Vista, do what 06TC lays out above. It will fix the issue 99% of the time. For anything that doesn't work in Vista no matter what, and you absolutely must have it, you have two choices if you don't want to get rid of Vista altogether: install XP on another partition of the HD and use a dual-boot app to have both of them, or, even easier, use Microsoft Virtual PC, and use XP as the OS on your Virtual PC.
