Yes.  Don't do that.  Or if you do, don't give me a copy. :-)


Seriously, the screen blanker I would like to use would fade the frontmost
screen's viewport's colors to or from black on command.  It would then
build the tiny low res one bitplane black screen in front.

You must use LockIBase(0L); while mucking with the viewport, and when
you fade it back up LockIBase(), then scan the list to make sure it
is *still* a viewport.  (damn, why are windows, screens and tasks
not serialized!!)  This should work without problems, but remember the advice
is worth what you paid for it. :-)

Blanking would happen after an interval of no input.device activity, 30
seconds or so default.  If I wanted to read a screen without disruption I'd
move the mouse to the bottom right corner; this would up the interval to say,
2 hours default.  If the mouse was shoved to the upper left drop the
default to about 2 seconds.

The bouncing clock, or checkmark on the blanked screen is nice, but make
it a sprite, and an option.
