Stop changing selection on mousewheel events
Submitted by Daniel Colascione
Please stop changing the selected entry in a combo box or option menu on scroll wheel. This behavior is incredibly annoying: scrolling should be an idempotent operation. There's often no way to tell that I've accidentally changed a setting by scrolling around in a dialog box, and there's often no way to undo what I've done, since settings these days take effect immediately. Mouse wheel events should do nothing but scroll.
