Windows Forum / Windows XP / Hardware / October 2005Microsoft mouse scroll wheel scrolls up & down at different rates!
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. My email address is LLM041103 at earthlink dot net. 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. >>Your video adapter drivers probably need to be reinstalled. >>Visit the support web site of the manufacturer of your video [quoted text clipped - 12 lines] > > My email address is LLM041103 at earthlink dot net.

Microsoft PS/2 Port Mouse (IntelliPoint) version 5.0.174.0. Bob I. wrote: >Just a guess, but try changing the mouse scroll wheel setting and test >differnt options. 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. My email address is LLM041103 at earthlink dot net. Glad to hear it. Happy scrolling! >>Is the O.P. using the defaule generic drivers or the enhanced Intellipoint >>drivers?? [quoted text clipped - 23 lines] > > My email address is LLM041103 at earthlink dot net. |
