: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

make sure your _orientation_ is set properly. 
(that'll keep em busy.. :-)

seriously, it sounds like your MacLayers TERMCAP is not
set properly.  ( the arrow key sends ^[OA, which is where I suppose 
the [A garbage comes from )

one problem I had is that the TERMCAP gets reset
to vt100 if you do rlogin/telnet after activating layers
(there is a simple work around if this is your problem )

I have also heard a rumor that vi on new Sun's uses the
terminfo database rather than termcap, which would seem to
throw a wrench in MacLayers (already shakey) scheme.

BTW does anyone know how layers decides to go into "vi" (fixed window)
mode.  It goes into "vi" mode with emacs, which bugs me since emacs
could handle window size changes (I'd at least like to try it).
