Another possibility might be the setting of the "Smooth Scrolling" option in Internet Explorer. I'm using IE7, but I think this option also exists in IE6.
In IE7, at Tools, Internet Options, Advanced (tab), the checkbox for "Use smooth scrolling" is under the "Browsing" category in the list. Change the value (checked vs. unchecked) and see what happens. If you don't like the results, just change that setting back to what it was originally.
