Scrolling In Firefox

Ever since I installed XP, firefox has been scrolling really wierd, ever since I installed XP. A line will roll down the screen, then it'll flip down a notch. It's driving me nuts. I can't really take a screenshot I'll try though.

 

Are you using autoscrolling? and smooth scrolling?

Tools>Advance

 

It gets worse with smooth scrolling, I've tried it. I'm using auto scrolling thuogh.

 

are you useing a laptop? or normal pc with a mouse?

 

I think it's the graphics card, it happend to me too, but I updated the drivers and the problem was gone.

 

What refresh rate are you on?

 

I acctually got non-official drivers and it fixed it.

Thanks for the help guys!
