yah I think my mouse is in need of new batteries....... the keyboard seems to be working fine still, but it's not as active as the stupid mouse. I have a big BOX of batteries but i'm so damn cheap to change them. I'm at the point where i'm getting MAD when I click on something and nothing is happening....(have to keep slamming on the mouse for it to click) guess I'll change them today for sure (cheap ole me still trying to squeeze another day out of the mouse)
