Indeed, maybe you have to copy the lower part everytime or so... Or, like in the
NOP demo, don't put usefull things near the border. NOP had a 'background
pattern', so the re-displaying could not be noticed.

Well, in the vertical direction it isn't such a problem, since I've never seen
any screen that needed set adjust in the vertical direction. And the changes are
not permanent.

In Unknown Reality and that Impact BBS promo. Maybe also in an ANMA demo (The
source of power?).

So, prove that and impress us with a FANTASTIC demo!
(I love demo's!)
