I bought a new wireless mouse + keyboard combo from Staples a few days ago. The keyboard is great. The mouse is a Microsoft Wireless Optical Mouse 2000. I bought it because it was cheap, and it fits the parameters I demand:
Black and silver
3 buttons only, including middle scroll wheel.
Well I hate it. The middle scroll wheel doesn't always work, I'd say it works about 40% of the time. Also, the mouse develops a serious lag every couple of minutes. Sometimes I'll right click on something, and nothing happens! I keep clicking furiously and eventually it will respond. I'll be able to move the pointer around, but not click.
I am unimpressed with the range of mouse, but it's not a big deal. The wireless base is not even 2ft away from the mouse.
Does anybody know why this could be happening?
