Do you have scrollbars enabled? It seems the scroll wheel is
just sending page-down events to the scrollbars, so it's just
silently ignored when they're not displayed.
Yes, that was exactly it. When I display the scrollbars the wheel
works.
So the bug report is really that the mouse wheel doesn't do something
sensible when scrollbars are not displayed. Perhaps they could be
active but invisible, or something.
Thanks - I think the wasted screen space is a fair price to get a
working mouse wheel, for now.

So, this is a different behaviour compared to the UNIX world. I
don't even configure scrollbars
,----[ nk-config.sh ]
| sh configure \
| --prefix=${PREFIX} \
| --site-includes=/usr/local/include \
| --site-libraries=/usr/local/lib \

and my wheel works. The same is true for my Cygwin build at work.

Yes, that was exactly it. When I display the scrollbars the wheel
works.
So the bug report is really that the mouse wheel doesn't do something
sensible when scrollbars are not displayed. Perhaps they could be
active but invisible, or something.
The below patch generates button{4,5}up events when the scrollbars are not
showing¹, so you can use the mwheel package Norbert mentioned:
(mwheel-install)
(setq mwheel-follow-mouse t)
It works for me, but I'm not familiar with win32 programming (or XEmacs
internals), so try at your own risk. Thanks for prodding me to look into
this btw, it's been annoying me a while.

Thanks for the patch. Would you mind resending to xemacs-patches,
with a ChangeLog? That's the best way to bring it to the attention of
people who do know win32, and ensures that it won't get dropped on the
floor totally.
