Technicaly it isn't possible -- X server wouldn't generate
"EnterScreenNotify" events, since Xinerama screens look like a single
large screen.
If this behaviour is really needed, fvwm itself should always
check if XineramaScreen(curx,cury)!=XineramaScreen(oldx,oldy), which can
be time consuming. And there's another pitfall -- screens may overlap, so
that "screen where the pointer on" concept becomes somewhat dubious (but
that's a pathological case, and we use this concept anyway for determining
a rectangle to clip menus etc. to).
BTW, Olivier, can you please tell where this behaviour can be
useful? I tried to imagine such situations with no results, but something
tells me they *must* exist.
