Query: Lousy mouse.

The keyboard is good. The mouse sucks! I need to use it for graphics (PDF editing, AutoCAD, etc.) and it get hung up and won't move where it needs to. Also, I never had the need to use the DPI button on the top of the mouse but it's worth noting that my DPI button does nothing whatsoever. I'm now looking for a second USB mouse. What a bummer and waste of resources, money, landfill space, and time.
