Hi Everyone.

I have been using Ubuntu for a couple of months as my primary operating system on a dual boot with XP on same drive. I have a problem with scrolling in pages using the scroll buttons on the right edge and using the mouse cursor to pull down the bar in the scroll control.
My problem is, it is not a smooth scroll but jerks as it moves downward and is very slow as compared to what it was originally. It does this in Firefox and also in open office on my desktop. I ran the X.org and put in my correct ATI Video card spec. and reset everything I know to be correct for my monitor, Keyboard, etc. No change.
Does anyone know what might cause the scroll to shift instead of a smooth scroll. ps. I have Kubuntu on another machine with same Firefox, Video card, etc and it scrolls smoothly. Any help is appreciated. Thanks. EdWh.
