building new system tomorrow. any issues with installing adobe production premium cs3 and prospect hd on windows 7 64bit? ill switch to vegas before i deal with the nightmare some associates are having with cs4.

That combination works for me on one of my systems, but not the other - on that one I get 'red upsidedown playback' (if you search on that you'll find several threads in this forum) and I have consequently had to upgrade to CS4 (which works OK).
