Is there a bit somewhere that can be set so that a(ll) window(s) will
disappear when MACL 1.3.2 is swapped out and reappear when the
application becomes active again?
No, there isn't. Certain future operating systems do, though, support
this functionality as a user option.
If you want it to happen under program control (rather than under user
control), you could try just moving the windows off screen.
The only problem here is that there is no hook in MCL that lets the user
know when MCL switches between foreground and background. Maybe we should
have something like *FOREGROUND-CHANGED-HOOK* which is a list of functions
to call after the value of *FOREGROUND* changes. (note: you can write
an *eventhook* that will notice when this happens).
What about the scrap handling functions? Don't those give you a
hook into switch-outs and switch-ins?
