Thanks for the response, Al. I think the most relevant question is the OS, which is Win98.

Happens in all apps
Mouse is MS Ps/2 mouse
Os Win98 SE
No 3rd party mouse driver in use

And yes, I did look in control panel and play with accessibility, and nothing seemed to fix it.

I strongly believe that this is a "feature" of windows with a setting, because I do recall seeing it before on other machines, and the behavior is very consistent and seems like the annoying kind of useless feature windows would have.

.>>Does anyone know how to turn off the automatic scrolling feature of windows? I'm not sure if that's the name for it - when I click on the up or down arrows of a scroll bar for more than a second or two, the scrolling takes on a life of its own and just keeps scrolling and scrolling and scrolling and scrolling and I can't stop it! It's driving me nuts. It just started happening - I must have done something to cause it to happen.
