bug#506: mouse scrolls the other buffer in Vista

[Vaidotas Zemlys]

Hi,

On Microsoft Windows Vista mouse scroll does not work as expected. If
you split windows and change to the new window, the mouse still scrolls
previous window. Steps to reproduce:

1. Run runemacs from unzipped download of emacs 22.2.
2. Open any file which does not fit into window.
3. Split the windows with C-x 3
4. Change to other window and try to scroll with the mouse.

There is a customizable variable, `mouse-wheel-follow-mouse', that
specifies whether the mouse wheel should scroll the window that the
mouse is over.  By default it is on, despite the behaviour being
slightly disconcerting.

When the mouse still scrolls the previous window is the mouse pointer
over the previous window?  If so, does customizing
`mouse-wheel-follow-mouse' help?

I usually change the windows with the mouse, by clicking on the window
I want to change to. So I always scroll the
window where the mouse and the cursors are. I tried changing this
variable though, there was no change in Emacs
behaviour at all.

After scrolling with the mouse, please press C-h l to view the events
Emacs has received, and send us the last few events (including any that
occurred around the time that you scrolled the mouse wheel).

Some mouse drivers on Windows do not send mouse wheel events, and
instead try to figure out which scroll bar is linked to the current
window and fake mouse press events on that instead. If this is the case,
you might get better results using a generic mouse driver instead of the
one that came with your mouse.

OK, I plugged another mouse, and the problem disappeared. The problem
was probably  caused by the driver of my
laptop touchpad.  (Asus F3Jp)

I am sorry for the delay, I use the windows only occasionally, so it
took time to find the opportunity to
boot into it again. Thanks for your help!
