Can anyone tell how to get a Microsoft Intellimouse optical wheel mouse to work properly. I'm not able to get wheel to scroll pages. Running Redhat 7x and 2.2 Kernel.

Thanks in advance.

Here's part of my XF86config for a Microsoft Wheelmouse. I don't see any reason why the optical should be any different. Of course it is a Microsoft product...

Section "InputDevice"
Driver "mouse"
Identifier "Mouse[1]"
Option "Device" "/dev/psaux"
Option "InputFashion" "Mouse"
Option "Name" "INTELLIPOINT MOUSE PS/2"
Option "Protocol" "imps/2"
Option "Vendor" "MICROSOFT"
Option "ZAxisMapping" "4 5"
EndSection

I installed the package 'imwheel' as well. I'm not entirely sure it was necessary.

You can use "setup" command and then select "Mouse Configuration" in the graphic interface to configure your mouse. In the item of "Mouse Type" you should select "Intelli PS/2".
Another way is to directly modifiy the file /etc/X11/XF86Config. In the Pointer Section of this file, set the value of "Protocal" to "IMAPS/2" and be sure that the file includes a line "ZAxisMapping 4 5". I use RedHat Linux version 7.1 and the Pointer Section in my XF86Config file looks like this:
Section "Pointer"
Protocol "IMPS/2"
Device "/dev/mouse"
ZAxisMapping 4 5
Endsection

Would that be the same for a logitech wheel mouse too?? Except for vendor of course.

I am not sure. But why not have a try? You can backup your /etc/X11/XF86Config file first and try the modified one. If it doesn't work you can use the backup file. It's safe.

Ran setup, and checked xf86 file for the changes. They were there, but still unable to scroll. ??

It was ok when I used RedHat7.0 with 2.2.16 kernel and now I update the system to RH7.1, it works fine too. But it seems that Netscape doesn't support scrolling. I cant scroll in Netscape both in 7.0 and 7.1. Other browser such as Mozill and Konqueror are fine. No problems in editors like Kword, Gedit. So I am not sure what happened to your system.
