RMAIL display problem

[Ken Harrenstien <KLH@MIT-MC.ARPA>]

Some additional data which supports the theory that a user-program or
ITS TTY bug may be involved:

All the times i have seen such an error i have been able to find duplicated
text on the screen and the supposition was that it was a duplicated
tcp packet or something like that.  I have seen this both internetting
from ru-net to here (from a 20) and i believe just within rutgers
(tops-20 -> tops-20 just on ru-net).

well maybe i should take back what i said last night.
I'm coming from a microvax vaxstation running a vt100 emulator window,
running decnet to a 750 (corwin) from whence i'm doing chaosnet supdup
to mc.  The window size is 94 wide by 55 high [i TOLD it 96 wide at this
end, you know how these things are...]  anyway, i have a two screen long
(at this screen size) message, and if i have it redisplay the first and
get a space (in rmail, go to next screen) before it finishes, it invariably
fucks up.

anyway, there ain't no tcp in THIS network path.
