Hi,

I have seen many people complain about this problem, both in this forum and
other third party forums but nothing seems to be getting done about it.
There are driver problems which are causing scrolling not to function
correctly in certain applications using Microsoft mouse products with the
Intellipoint driver software under Vista. All such applications (in my
personal experience) worked correctly under Windows XP with the exact same
hardware.

The primary symptom is faults with upward scrolling, in some applications
(e.g. Google Earth) upward scrolling is not recognised at all and the
application scrolls down (which is Zoom In) no matter which way the wheel is
turned. In other applications (e.g. Opera Web Browser) upward scrolling is
also mis-interpreted, scrolling up in these applications cause the page to
jump up an huge chunk on the first move of the wheel, then start scrolling
down again (even though the wheel is still being pushed up).

This is my list of problem and problem free applications so far:

Upward scrolling does NOT work:
Google Earth
Opera Web Browser
Itunes
FarCry

Scrolling does work:
Windows Explorer
Internet Explorer
MS Office 2003 products
Mozilla Firefox
Mozilla Thunderbird
MSN Messenger

Please hurry up and get this fixed MS! It's extremely frustrating.
Seb.
