beta 2 glass effect s

Hey Guys,
I installed beta 2 (5384.4) a few days ago and installation went through without a hitch... no problems encountered as of yet.. the only thing that is really bugging me is that I can't seem to get the glass effect to work. I have a Nvidia Geforce Go 5200 video card, and Aero ran just fine with the previous Vista builds (by the LDDM alpha drivers).
I've tried every single driver and forceware available:
88.61 87.45 87.15 75.03
I even installed the Nvidia driver through the Windows Update Server, still didn't work.. although gave me a nvidia control panel.
None of them seem to turn the glass effect on, in this build. Even tried to force it through the registry but no luck. And still trying to by-pass activation.. I'll prolly uninstall it if I can't get the glass effect to work in a few days.
P.S: Is anyone else finding that the "customize color scheme" section is buggy? I cannot see the different glass colors nor do the "ok" and "cancel" buttons work.
Cheers.
