I use both my trackpad and an external mouse. I have the tracking speed set to the highest setting, which is what I prefer for the trackpad. But it is too slow for my external mouse. Anyway to make it go faster? And the second question is, when I plug in my external mouse, is there a program that can tell the tracking speed to go up to where I prefer the external mouse to be? And when I unplug the external mouse, will it go back to the preferred trackpad speed?
