Wheel Mouse

I don't know what happened, but one day I noticed that whenever I'd scroll with my wheel mouse, instead of each scroll being equal to three up or down arrow clicks, it's now equal to a whole page. The thing is, I did nothing to change the settings. I've tried to find the setting but to no avail. I'd like each single scroll to be equivalent to three up or down arrow clicks. Can anyone offer any solution for me? I'm using Microsoft Wheel Mouse 3.0 PS/2 compatible with Microsoft Intellipoint 5.2 drivers. Thanks.

 

In the control panel under Printers and Other Hardware in XP, will be the Mouse settings. Click on the wheel tab and check the setting and reset it to your prefs if possible. It has its own category in the Classic menu.
