Before I throw this mouse in the round file, I should probably get an opinion. The mouse is a Microsoft wireless 2.0. The cursor is practically impossible to move at times, even with repeated dragging of the mouse. The mouse does not want to left click, with repeated clicks being necessary. I don't know if this mouse is transmitting properly?, but i've changed the batteries and that doesn't help either. My patience has run out with this thing! Is there some trouble shooting that I can do that I have not already done? Thanks!
