Microsoft mouse scroll wheel scrolls up & down at different rates!

[Jonathan Sachs]

Its scrolls down normally, but scrolls up uncontrollably fast. If I
roll the scroll wheel toward me very slowly I can see the window
scrolling down a line at a time. If I roll it away from me very slowly
I can see the window scrolling up a page at a time!

This appears to be a problem only with generic applications. With
Windows itself (e.g., Windows Explorer) and Microsoft applications
like Internet Explorer and Word, the scroll wheel behaves normally.

The mouse is a Wireless IntelliMouse Explorer 2.0 (model number 1007).
I'm using it with Windows XP and SP1.

Your video adapter drivers probably need to be reinstalled.
Visit the support web site of the manufacturer of your video
card adapter and download the latest drivers.

Before installing them, uninstall the old drivers. In your
Control Panel, open the Add or Remove Programs applet
and look for your video drivers to uninstall.

If you happen to have a notebook computer, visit the notebook
manufacturer's support website to download the correct video
adapter drivers for your specific notebook model.

After installing a fresh set of drivers, right-click on your
desktop and select Properties > Settings, change the Color
Quality to "Highest (32 bit), then adjust your Screen Resolution
to your liking, then click on Apply.

I checked the manufacturer (ATI) web site, and found that the latest
driver available for download is the one I already had installed.
Nevertheless, I downloaded and reinstalled it just to see if that
would help. Unfortunately, it did not.

I hope you can suggest another way to approach this problem -- perhaps
one that is more closely associated with the mouse. I am not familiar
with Win XP driver internals, but just in terms of function, I cannot
think of two GUI components that should have less potential for
interaction than a display driver and a mouse driver.

Just a guess, but try changing the mouse scroll wheel setting and test
differnt options.

Is the O.P. using the defaule generic drivers or the enhanced Intellipoint
drivers??

Microsoft PS/2 Port Mouse (IntelliPoint) version 5.0.174.0.

Hmm, very interesting! The problem appears to occur (with some
applications but not others) only at the slowest setting.

The only two relevant options appear to be enable/disable vertical
scrolling and enable/disable accelerated vertical scrolling. Changing
the former would be self-defeating; changing the latter did not affect
the problem.

I found a newer mouse driver on Microsoft's web site and installed
that, but it made no difference. Apparently this is a mouse driver
bug, and is not yet fixed. Does Microsoft have provisions for
reporting something like this?

Increasing the scrolling speed one notch is a viable workaround,
though. Thank you for leading me to discover it.

Glad to hear it. Happy scrolling!
