Mouse Wheel Odd Behavior

[phaseburn]

I've been using wheel mice for several years on several gentoo boxes, and, this is the first time this has ever happened to me... any help in figuring it out would be very much appreciated...

I have a gentoo workstation that I just reinstalled. Before I did so, it was working fine. Had gnome 2.4 on it, had a Logitech Optical wheelmouse on it (nothing fancy). Worked great.

I reinstalled it from the packages dir on another workstation (I use -march=i686 and almost identical USE flags, and it's a dual athlon mp 2400, this is a P3 1GHz). The reason for reinstall was that I upgraded the HD, added encryption to it. I also changed mice (though this isn't the reason for reinstall)... It's using a Logitech Dual Optical mouse now...

After installing X, Gnome 2.4.2, and my usual applications, I noticed something odd... The mouse wheel is not behaving properly... Scrolling down works fine. Scrolling up opens the right click menu. It does this in all applications, the desktop, everywhere. This mouse works fine on another gentoo box (also running gnome 2.4). Another mouse has the same problems on this box. It's a config issue or something local to this box, as best as I can figure.

I use Sawfish instead of Metacity, and not just on this box - on all 3 of my gentoo workstations, including this one before I reinstalled... My X config has the ZAxisMapping option set properly to "4 5". Removing this option still triggers the right menu on moving the wheel up, but stops the scrolling when moving it down.

I've reemerged the following packages in the hopes it helps:
gnome-vfs
gnome-session
gnome-desktop
librep
rep-gtk

Nothing's helped, unfortunatly... So, any suggestions on how to fix my mouse would be much appreciated.

I had a similar problem with my mousewheel. I couldn`t figue out why it didn`t work. However, I solved it by specifying a different driver in XF86Config. I`m not sure what options you have for drivers but:

Option "Protocol" "IMPS/2"

worked for me.

Yea, I'm using that already, as well as the ZAxisMapping option... It's only half the wheel that doesn't seem to work...
