RPF seems to dynamically switch screen modes - its first screen is

will auto-center the first RPF screen in 80x24 mode. Vista will make
the terminal window larger or smaller.
I don't know how RPF decides what size of screen image to send to a
user, but in ISPF (which I last used in early 2000) one had to tell it (in
some settings at option 0, if I remember right) what kind of terminal
one was using. I expect that had to match the way one's terminal
emulator was set up.
I also expect there's a difference in behaviour between (ISPF/RPF) panels
where the panel layout is defined in a static/fixed layout, most likely as
n rows of 80 bytes, and those where the panel is in essence a title line
followed by a dynamic (stretchable in both directions) area which a
program - knowing what size of the screen the user wants to use -
can make any shape it likes.
I think what you're seeing is the down-side of software terminal emulators
being able to be all things to all people, in a way that the original hardware
could not.
