Need help w/AVT Vnews bug

[Bob Fishell]

(oo) <- a pair of bleary eyes

I have been trying to get help with an extremely irritating bug in
vnews.  Whenever I try to read the first article in a given newsgroup,
vnews transmits a character which causes my screen to scroll up one
line.  When this happens, the text previously on the screen is often
not properly removed, and when I move on to the next article, the
screen is scrolled down to where it should be, and some text again
remains on the screen.

A ^L will redraw the screen normally in each instance, but it's irritating
to have to do this every time I move on to a new newsgroup.

I have a similar problem with articles that are one line longer than
an even multiple of the number of lines that make up a full screen.

My terminal is a Concept AVT (Human Designed Systems, Inc.) with 8-page
memory.  The default parameters, which I use, set it up to look like
a DEC VT100.  I posted this problem locally a few months back, and got
no real solutions. I'd like to hear from anybody who's found a solution
for the problem.
