New Bug (and its symptoms)

Well, it's got to be conflicting somewhere, otherwise I'd say that you need a new mouse. And it looks like a new touchpad, too.

It sure sounds like a conflict somewhere between Dom and your system. I would not blame the mouse though, that is probably just how the glitch is happening to manifest itself.

I would suggest a clean re-install of Dominions. That often clears up weird problems like this.
