mouse wheel only in 1st window?

mouse wheel only in 1st window?

[Rainer Volz]

Hello,
I recognised something strange in Emacs 21.3: when I split a window,
the mouse wheel (the mouse wheel replacement functions of the laptop)
only works with the first window, even when I switch to the second
with C-xo. I there a setting to manipulate?

Thank you
Rainer

Did you turn the mouse wheel on in your .emacs?

What does C-h k [mouse-wheel] say? Some mouse drivers, especially for
laptop touchpads on MS-Windows, try to simulate a drag of the scroll
bar instead of sending the default mouse-wheel event. This is
annoying, because such drivers make the assumption that a frame only
has one vertical scroll-bar, and Emacs can do nothing about it.

Mouse-wheel-mode was enabled, if I disable it, the behaviour is the
same.

Emacs says:
<vertical-scroll-bar> <mouse-1> (translated from <mouse-1>) runs the
command scroll-bar-toolkit-scroll
   which is an interactive compiled Lisp function in `scroll-bar'.
It is bound to <vertical-scroll-bar> <mouse-1>.
(scroll-bar-toolkit-scroll EVENT)
Not documented.

Looks like it is the touchpad driver, not Emacs.
Thank you.

Some touchpads work well with a generic PS/2 driver. But make sure
you know how to operate your PC with the keyboard before you start
playing with mouse drivers.
