When typing my cursor randomly jumps all over the place. When i'm typing a letter in Word or typing in E-mails. Very disturbing. This is my first time using the vista forum. I hope i'm in the right forum...thanks tom

Out of sheer curiosity are you using a laptop?

Hopefully your mouse will have the ability to customize, and should provide some preferences settings. Sounds like the sensitivity is up too high, and if you have a laptop with the ability to set your "Palm Check" that would make the mouse jump around too. Let us know what kind of mouse/touchpad you have, and perhaps we can help you with more specific directions.
