Vertical scrollbar issue - dn 2 pgs, up 1 pg

[Don C]

With a recent global system update (required by my
employer), my vertical scrollbar began acting up in
Internet Explorer. I think it has something to do with a
Microsoft patch that was part of the update.

When I click on the lower portion of the scrollbar, which
should result in scrolling one page down, the browser
scrolls down 2 pages. When I click the upper portion to
go back up, it scrolls up 1 page.

This only happens in the IE browser. Every other
application functions normally.

Before anyone makes silly suggestions, I've already tried
the obvious things. Whether smooth scrolling is checked
or unchecked in the Internet Options advanced settings, it
still happens. It happens with both the trackpoint device
(I'm on a laptop.) and the external mouse, and I'm
not "accidentally double-clicking" or any such thing. I'm
not a novice user - nor am I stupid, crazy, or retarded.

If anyone has any credible explanations or reasonably
sound ideas as to the possible cause, I look forward to
reading them.

I'm running IE version 6.0.2800.1106, in case anybody
thinks that matters. I think the latest patch that was
installed is probably more meaningful to solving this
quirk, but that information isn't readily available, since
this was a corporate deal.

Thanks.

It's a known issue but Microsoft hasn't said when it will be fixed. Make it
more interesting: position mouse close to the bottom of the scroll bar and
scroll will advance less than 1 page. Somehow it takes the distance between
and creates a new screen.
