I've always installed my Poser apps in the root directory, C:Poser #, even under Windows XP Pro.  And I like to keep machines consistant so I avoided any issues with UAC.  I was fiddling with UAC levels and think I did turn it off - have to check that - I'd at least like to run it at a reduced level.

I really don't plan to go out on the Internet with this new machine.  I don't think I need a lot of security measures in place.

Poser 7 DID indeed load and raytrace my old scene.  Seems to be working like a champ!  Increased bucket size to 16 and it's working with Ir caching at 75 and it's raytracing the picture pretty quickly.

Windows 7 certainly seems solid.
