Hi Jason,

thanks for your quick reply!

It's a Logitech mouse with the latest Logitech driver, and the middle
button is configured as `Double-click'. I uninstalled the driver, as
you suggested:

After a system reboot (as required by the driver deinstallation), it
works! The middle mouse button is mouse-2 now, and I can
yank. Cool. But I guess there are many Emacs installations out there
where it is not working... having an extra mouse driver installed and
using the middle button for double-click is probably not too uncommon.

What I mean is: although this is a solution, a solution that would
work together with the mouse driver installed would be better,
IMHO. Couldn't there be a variable that allows for toggeling the
function of the middle mouse button in Emacs, between e.g. the
`system-wide setting' and `mouse-2'?

Now I see that the middle button seems to be dead in all applications
but Emacs. Clicking or double-clicking a program icon on the desktop
with the middle button doesn't do anything now. So it's not a solution
:-(

No. When I tried this, I started emacs with `runemacs -q
--no-site-file'.

Even now, after uninstalling the mouse driver, I get (again with
`runemacs -q --no-site-file'):
