I thought I should tell you: you guys have a small bug in your footmouse. It seems that after a few days of use, there's some electric charge build-up somewhere such that it exhibits the problem I had before -- moving to the left is half as slow as any other direction. The problem is fixed simply by unplugging the footmouse and plugging it back in. You might wanna put this "errata" on your web page. P.S. The footmouse is great! I love it!
