I have finally done my first DLI <yawn> so what's the big deal?
Well - I first did the following.  I changed the display stuff at
some point on the screen, to change the color registers and the character
set, and relied on the built in vertical blank routine to change them
back for the top half of the screen again.  Well, it seems like
CRITIC gets set a lot more than I expected, as there was a lot of
flicker on the to half.  So, I made an addition to the first stage
VBI to set the character set and colors back all the time.

I still get some flicker (it seems to miss either interrupt from time
to time, say once every 10 seconds)!

Is this a reality in the Atari, or did I not set something up right?
