#SCROLL WHEEL GOES UP AND DOWN DRIVERS#

On the same system, the Microsoft IntelliMouse Optical USB and Logitech LX3 work fine. Specific example: This issue has been replicated at SSC with the Microsoft Comfort Mouse Optical 3000 as well as several other generic mouses. one of the devs was meant to be looking into changing the handling but that never happened i believe and without knowing what mice exhibit this finer level of scrolling (as i need a new mouse but canвЂ™t get a definite answer) iвЂ™m not going to shell out for something that wonвЂ™t help. ItвЂ™s due to the handling of the delta value passed in the wm_mousewheel message assuming a delta of 120 but some mice have a smaller delta (as is allowed on vista/win7) which breaks the previous logic.

If installing the latest mouse drivers does not solve the problem, and the latest application software updates do not solve this problem, the best solution is to replace the mouse. The root cause appears to be that the software in question is that the mouse being uses can send more fine-grained mouse wheel input than the software in question supports. In some cases this has been reported in Vista as well, but almost never older OSвЂ™es (such as XP, 2000, etc.). This may occur on hardware that is Windows 7 approved and should work. In some applications in Windows 7, it may work fine, in others, it either does not work, or does not scroll down (scrolling up still works in some cases). A mouse with a scroll wheel that works fine in Windows Vista, Windows XP, and other OSвЂ™es does not work properly in Windows 7.
