Help disabling mouse wheel tilt in 10.10

Hi, I installed Opera 10.10 under Gentoo x86_64 a few days ago. I thought I should give it another shot, since the last time I tried Opera must have been 10 years ago. Anyway, I really like it so far, but I have a problem that I can't seem to fix:

For some strange reason the left-right tilt functions on my Logitech MX610 mouse wheel are mapped to scroll up and down on the page. This is REALLY annoying because I apparently don't have the skill to middle-click on the mouse wheel without also tilting it left or right. So, 90% of the time, when I try to middle-click a link in Opera to open it in a new tab, I end up scrolling the page so the link is no longer under the cursor, and pasting the contents of my clipboard into the Opera window. This has never been a problem for anything else because tilting the wheel isn't mapped to anything in any other software I use, and I don't really understand why left/right would be set to scroll since turning the mouse wheel does exactly the same thing.

"xev" tells me that the mouse wheel tilt is buttons 6 and 7, but Opera doesn't show them as mapped to anything in the "shortcuts" section of Preferences. I've tried to map them to something else, but they never change; tilt left and tilt right always scroll the page, no matter how I map them in the "shortcuts" section of preferences. I'd prefer to map them to NOOP, but I can't find a "do nothing" action in the mouse setup. Even if I could, it seems to ignore it, no matter what I map them to.

So, how do I get it to stop scrolling on left/right tilt? This is almost a deal-breaker for me, as I almost always open links in new tabs with middle clicks, and I can barely do it in Opera with the tilt-scroll active.

Thanks.

Have you gone to Preferences > Advanced > Shortcuts and removed "Button6" and "Button7" from the mouse setup? Actually by default they were mapped to Back and Forward ... maybe Gentoo is one of those distros that is remapping the mouse buttons. (Mandriva does.) See if they have imwheel running in the background ...

Oh, thread moved to the Opera for UNIX (Linux) forum so that other knowledgeable users find it.

Yes, I've remapped and removed buttons 6/7 in Preferences>Advanced>Shortcuts, and neither seems to do anything.

I have noticed that the buttons do what you would expect when the window is narrow enough that you can scroll horizontally. It only scrolls up and down when there's no scrolling do be done to the left and the right. (I'd still prefer to have them do nothing, though.)

Gentoo doesn't really do anything on it's own; if it was re-mapping the mouse buttons, it would be because I configured it to. I'm running xorg-server 1.7.6 with HAL support, and there is no device section in my xorg.conf for the mouse. Imwheel is not installed, either. Although, maybe I should install it and see if it helps...

Thanks for moving the post to the correct forum.
