I just updated to the latest beta and it didn't go as smooth as others. Initially under XP it gave a message about updating the video driver. Upon reboot after the splash screen it just stayed blank. I was able to log in to Vista RC2 and everything went smooth. Safe mode under XP was fine, I noticed that when I captured control there were still two pointers the Windows one kept slowly moving down the screen. I ended up having to use the keyboard to navigate around. In the end I managed to get the video sorted under Win XP. The only remaining problem is: Windows finds a new USB controller but it fails to detect any drivers. Even if I try and do a manually driver install none of the generic ones work. Removing it in the device manager and re-installing causes the same result no driver found. I also noticed when I switched to coherence mode or shutting down the screen will briefly slide as if it was switching monitors & slide back again but I only have one monitor. The lack of finding a USB controller driver is the main bug I see so far.
