	Why is this a problem?  The CLI will only be interlaced if one of
the screens is dragged to reveal the other one.  If the CLI has the screen
all to itself, it won't be interlaced.  Apart from making the CLI screen
jitter, there are no other adverse effects.

	There are other compelling (somewhat esoteric) reasons for using
interlace, too...

	'Fraid not.

	Nope, I'm calculating everything on the fly.  Mind you, I'm cheating
a bit...

	Perhaps you're thinking farther ahead than I am, but what other task
might want to claim the screen?  My ViewPort-oriented program is used just
for viewing 3D stills.

	It'll all be in the manual, as part of the released kit.  So
everyone who buys one will find out how it's done.

	We liked the Sega glasses because they have built-in neutral grey
filters, and they're relatively cheap.  Your glasses sound interesting; who
makes them?

My Official Employment Status
-----------------------------

	I am currently working with Reichart Von Wolfsheild (the author of
FirePower) on a project.  The official straight-line is that we're working
on a Superconducting Compact Disk Player :-).

	Actually, I'm working on something else, but I want it to be a
surprise...
