I use to have Vista 32 installed and I just recently installed Vista 64. There are a few features I had with the 32bit version that I do not have with the 64bit version. FIrst that I was able to have the Areo view with the 32bit version which is now not available (the transparent dialogs and other stuff.) Also when I did a control-alt-tab when I was playing video I could see the video in the application change dialog. I no longer have that feature either. Both the 32bit and 64bit were sp1. Any ideas why I am missing features in the 64bit ulimate version that I had with the 32bit version? THanks.
