I was a doctor office complaining of having pains in fingers. he suggested I get a Ergonomic Optical mouse. man it like night and day.
I can play for hours with no pain. now all I need to find a good gaming one. this one only has 6 buttons on it. good for most things. I just like to micro mange things.
opps sorry. yeah it ones where it fits in side of hand. cant link post or would. I used all day now. it actually really nice. Ever see star track symbol it like that style and it on side.
sorry really do not visit forum often. I found this work around.
