Possible Mouse-Wheel Scroll Bug in Windows XP

Recently I have noticed that when I roll the mouse-wheel to scroll downwards in Windows XP the window occasionally scrolls upwards.  This is rather annoying as it makes window scrolling visually jerky.  I have seen it when using Firefox and when using Internet Explorer.  I have also seen it on more than one installation of Windows XP.  It would appear to be a bug.

I now think this is probably a mouse hardware problem rather than a software bug.  It seems to be getting worse.

I eventually fixed this problem by using narrow strips of cardboard to scrape out a large lump of fluff that had accumulated around the axle of the mouse-wheel.  So it was a hardware problem (assuming fluff counts as hardware and not software).
