I have had no problem with Windows 7 here. In fact, it was very intuitive but wouldn't work with my WinXP. I understand a lot of people's computers are different, but I've NEVER in my 10 year Senior Systems Administrator career heard a company tell its customers to use a different computer period. I was told that by support when my Pitch Factor wouldn't work on my XP computer. I got no more support on the issue and had to go on my own. I don't know what the right combination of steps I took resolved my issue, but after doing my own troubleshooting I was able to get it working flawlessly, without support.
