S.M.
Keisha,
I noticed the same thing with the mouse in our system (my 4 y/o was given it for Christmas). I am going to try the things the last poster gave, but think it may just be the design. It keeps sticking in one place, and my girls pick it up off the pad and try again (works abt 50% of the time). I also see them rolling the thing around and banging it on the mouse pad like adults having the same issue with their mouses :o) Some things just seem to be natural - like shaking something with batteries in it to make it work .
Good luck.
S.
