I recently purchased the Desktop 700 combo, but I am too having mouse issues. If I leave the mouse still for around 4-5 seconds, it goes into a half-sleep state and when I next move the mouse, it doesn't respond for the first fraction of a second, resulting in a very noticable jump and less movement than I expected. If I move the mouse really quickly, then I can beat the sleepiness altogether and the pointer won't move at all. Has anyone else experience a similar thing? Am I just getting what I deserve for cheap hardware, or is my mouse actually faulty?
