I guess its a Mk3. I had problems with my Mk2, but now I have a Mk3 its fine on my system. What
type of mouse is it? Not every single make will work. ALL Logitech mice work with it though. That is
probably what is the problem. The Mk3 supports more than the 2 I think, but its still not perfect in
the support department. If you get one it does support you will get very little problems.
