Under X11, wheel-up and wheel-down events are buttons, so they get
pressed&released like any other (actually, it seems to be the case for
the hardware as well, so it's not a complete invention of the X11
layer). I.e. when you turn up the wheel by 3 steps, you get 6 events.

You also get such a down in that case, but that's a down-mouse-2 rather
than a down-mouse-4 or down-mouse-5: pressing on the wheel is
a completely different button from "turning the wheel".

Yes, tho it's mostly not Emacs's fault. X11's handling of wheels is
not great.

That's a general problem under X11, yes. There are various ways to work
around the problem, but it's a source of annoyances. Typically, the
additional buttons will then appear not as mouse-4/5 but for example as
mouse-6,7,8.

Thanks, it's installed in emacs-23, closed,
