But the problem is not actually Gnome's window manager -- it works
beautifully with *every other app* *except* Squeak.

At first I thought it was a chink in Fabio's fantastic *squeak.sh* script,
but the same problem occurs even when I launch *bin/squeak* directly.

I sense it's something to do with *how* it's being executed by Linux and/or
Gnome...  The way it's supposed to work is:   when the full command-line (I
think) is exactly the same, it knows to re-top the window for the existing
instance invoked by that command, UNLESS the [Shift] key is pressed, in
which case, it spawns a new process instance of the command again (and
producing another window running instance).

It works with everything except Squeak...
