Does your laptop's touch pad ever does crazy things?

I know mine has. Sometimes it clicks on things I don't want it to click on.

I really don't like the touch pad on my laptop, it is so sensitive.

It also does things on Menewsha I don't like either. :( It clicked on something I didn't mean for it to click on. :-/

Anyways has this ever happened to you?

If this topic has already been posted, I apologize.

Edit: as in touch pad, I mean the mouse that comes already with the laptop.
