It's so weird. I can do absolutely everything else on my computer but when I open Windows Media Player to listen to some music the pointer on the screen starts vibrating. Now i'm no techy, by far. I thought it might be my mouse so I wen't and bought a new one. A wireless one this time instead of having to worry about that stupid cord. But as soon as the player opens, the pointer on the screen starts jumping up and down. I don't even have to be playing music yet for that to happen. And it doens't matter if I play music or not. The eniter time the player is open, the stupid thing vibrates. Even if i minimize it and jump on the internet. Anyone know what's going on? And try to dumb down your responses because as I said, i'm no techy.
