|Dollar mouse shipped direct to my house from Singapore|
It worked fine for a while, but then it started acting really flakey and I thought, well, what did you expect for a dollar? But then it went back to working okay, and then it went to being flakey again, and this time I realized it was because my left hand was reaching across the keyboard to the number 8 and 9 keys and I was letting my hand rest on the touch pad. So, nothing wrong with mouse, it's just the touch pad giving me trouble. Again.
Big advantage of mouse over touchpad: right click. There's probably some key combination that will allow you to preform the same function with the touchpad, or there might be some magic finger gesture you can make, but you know what? I don't care. I have a mouse and I know how to use it so that's what I am going to do.
