Sorry, this isn't really about the "telnet question", my news system
is lightly toasted.  Anyway, it's about animation:
 
To produce flicker-free animation, I've been told to either use an
offscreen grafPort and transfer it with CopyBits or define a vertical
blanking procedure.  Unfortunately, nobody mentioned exactly how to
do any of the above.
 
I'd appreciate any type of suggestion, be it an example of the above
or suggestion for a different strategy.  If it's an example, I'll need
a simple example (ie: a square flying across the screen) so I won't
have to flood my mailer (and wait weeks for responses) to figure out
how to do it.
 
Finally, PLEASE send all responses in E-mail.  As I said, my news
system is lightly toasted and doesn't like threading, etc.  Especially
since it wouldn't be threading the proper topic anyway...
