I think this problem is fixed in 0.9.51 (to be released
soon).
The major new feature in the 0.9.51 version is support
of session save/restore. By pressing a key (F12), the RAM
and other state information is saved to disk. MOL can
then restart the session almost instantly at a
later time. On my G3 I can restart a session in
less than two seconds.
The session save/restore feature also opens up for
video hardware acceleration (by letting MacOS access
the video hardware directly). If MacOS is given
direct hardware access, then the MOL console must be
active as long as MOL is running. This could be achieved
by saving/restoring the session at console switch
(switching to mol in a X-window whould thus not be possible).
I'm also considering adding a function which restarts the
MOL session as soon as a particular VT is activated.
Cheers,
