xfwm4 and moving windows

I believe someone brought this up on the ML recently.  You might want
to search the archives.

In a (large) nutshell: X seems to think you're double-clicking when
you're in fact single-clicking.  You can check this by installing the
"xev" program.  Run it, and single-click in the window that pops up.
Watch the terminal where it started and see if you get one press event
and one release event, or two of each.

One possible cause is that you've installed both xf86-input-mouse and
xf86-input-evdev, and they've both detected your mouse so you're
getting duplicate events.  Try uninstalling -mouse and see if that
helps.  If it doesn't, put -mouse back and remove -evdev.

Another possible cause is that there's something in your system that's
causing X to see two mice for your single mouse.  Maybe you have some
kind of emulation mode running, or... something, I dunno.

Either way, you can also look in /var/log/Xorg.0.log to check out
what's going on with input device detection.  The 'xinput' program can
also list all your input devices.
