dragging a window under gnome using the left mouse button [i
have gnome/enlightenment] causes any programs with an X
interface to freeze and not update their display until I
released the mouse button.
Notable with xmms , top running in xterm .....
xmms music stops , graphic display stops.
I'm afraid I don't have time to look more closely into this
and provide you with more info. It may even be a bug in X.
could be a problem if someone has a realtime app running
under X which then proceeds to die nastily , just because
the person is drag selecting.
email me if you want more info on my setup.
Since E grabs the X server this cannot be fixed.
