How do I turn off the midclick+scroll Quick Menu shortcut?

There's a seemingly built-in mouse shortcut that brings up the Quick Menu when the game detects mousewheel scrolling while I'm holding the wheel down. Since I use middle click (the wheel) as a button, and charge my techs, this means that the slightest twitch of my finger can cause the Quick Menu to unwantedly pop open in the middle of combat (and interrupt my charge, just to add insult to injury).

I've gone through the options, and I think my eyes must be glazing over at just the wrong time, every single time, because I cannot for the life of me find a way to turn this off. Can anyone shed some light on this for me?

Never mind, research shows it was actually because of a wheel tilt setting that I've since fixed. Can I have a mod delete the thread, please?
