Well, here's more news about Win 7...
It died!
The disk it was installed on (granted it was my smallest, oldest IDE hard drive) just died. When I got home the screen was black and there was this distinct clicking noise coming from one of the drives.
There's not much lost as the disk contained only the windows install. All Program Files were installed on another drive, as is all my TG work. But that's unavailable now, until I install Windows again on another drive, preferably a new one.
So in the mean time the only projects you'll see from me are new ones, as the running projects are unavailable.
But I don't think Windows 7 is to blame, so I will continue to test it with a new installation.
The only downside to the OS is that I've been unable to install PhotoShop CS4 (not even a fresh trial version downloaded from the Adobe site). But that seems to be system related as well, so maybe a new hard drive will fix that as well...
