I'm having a problem when I run vi through MacLayers.  When the
cursor is at the bottom of the window and I want to move down a
line, the text doesn't scroll up properly.  Instead, I get a
beep and the characters [A appear, followed by the line that
should have been scrolled into place.  Apparently, MacLayers
isn't interpreting the vt100 scroll-up command properly.  This
happens whether or not I have the Unix-side layers manager
running, whether I'm using the stock vt100 TERMCAP or the
customized one supplied with MacLayers, at a variety of data
rates (from 2400 to 9600 with compression) and with a variety
of settings of the number of bits and parity (though I don't
claim to have tried them all).  It does NOT happen when I run
another terminal program (Zterm).  This problem makes vi nearly
unusable on long files.  Anyone know what's going on?
