Close, but no cigar.  I changed Interleaf's memory allocation to 6
megabytes, and the symptoms changed completely.  It didn't complain
about memory.  It did go through the copyright notice and draw the
Interleaf desktop (accompanied by continuous disk chatter), then it
bombed with ID=08 (dsTraceErr).  I tried running without Multifinder,
with similar results.  Since the desktop had been left open, it got as
far as putting up a dialog about breaking the lock, then bombed again.
(Same ID.)

Theory: Interleaf does everything for itself, including cursor
handling.  Since it bombs at exactly the point where it first puts its
own cursor on the screen, I'm guessing that it meddles with the
interrupt service or cursor VBL in some way that VIRTUAL didn't
anticipate.  If this is true, the prospects for a fix are not bright.
