hi
ive just installed windows vista beta 2, and all is fine, a bit slugish in some places but i am getting a memory upgrade to solve that.
aero though doesnt seem to want to work properly for me though, the features of it do such as the windows flip 3d (windows key + tab) and the glow round the exit, minimize and maximize buttons at the top. though when i try to go into the personalize settings and try to enable the transperency settings in the colour scheme and then press ok, nothing seems to happen, i open up the colour scheme window again and find that the transperency glass box unticked it self.
can anyone give me an idea on why it does this??
thanks
