I responded to the first post about windows 7 Beta (Beta being the operative word here) that extreme care should be exercised re: independent partion for it, and finding out whether uninstalling it would be a problem.
I wouldn't expect it to work with a lot of customization software at this point, or perhaps with drivers....
Also, playing with Beta's...sorta like playing with razor blades, in a way...the cutting edge usually does just that.
MS is basically giving a whole lotta people the opportunity to turn their computers into "guinea pigs"....
Hope you can revert to your prior OS and enjoy Deskscapes, lordwilliam.
