I just tried this software and I found it so great, I use 90 degree rotate and I don't need to scroll my mouse all the time when I surf the websites and for my outlook.

No conflict whatsoever in my old PC, AlthonXP 2800+ cpu, ati 1300 agp display card with 1GB ddr400 ram; It works just fine. It fits my old 18"LCD (I bought it about 6 years ago) and runs on 1024x1280 resolution.

never ever use pivot pro software.
recent...screwed up my GeForce pci-e video driver...never get back to work.
formatted hdd and reinstalled windows.
conflict, shutdown windows, restart windows automatically...
suck!!
