Hi,
I just discovered you product and I am using it on Windows 7 without any real problems. I had used Virtual Desktop from Star Dock Software but they dont support Window 7. A feature they had I wish yours had was the ability to place the Desktop preview / manager in the taskbar. That way I could switch desktop by showing the taskbar (I usually keep it hidden) and clicking on the desired desktop. This way I didn't have extra stuff (preview or manager) on the desktop. Just a thought. You have a really cool product.
