The center button on my corded mouse will not scroll up/down when I just roll the button. It will scroll if I press the center button and get the up/down arrow icon.
The mouse does not have a ball underneath - it's a red light. I think the mouse is full of cat hair ( ironic, huh?), but I'm unsure how to take the mouse apart.
There is a small Phillips-head screw underneath, but I'm too chicken to take the mouse apart.
Maybe I should consider a cordless mouse? Any recommendations for a 5 year old Dell desktop?
