Query: Mouse is junk

I bought mine for my 3 yr old directly from Leapfrog's site. My daughter enjoyed the games, but it didn't keep her interest long. She got more and more frustrated as she used it because the mouse is terrible and does not work well. It would have been nice if it had a real jack plug in for a real mouse, instead of a play one. The mouse pointer freezes and won't move. Even after restarting it, it is frozen and doesn't work. Now all the games we've bought are worthless, and can't be used anymore. I did like that it was a real QWERTY keyboard and she learned eye hand mousing coordination while it lasted.
