This usually indicates a bug in the system's "curses" library.

When curses receives an ESC character (code 27), it waits to see if it
is followed by other characters which constitute a recognised escape
sequence (e.g for cursor keys, function keys etc). It should only wait
for a short period; if no other codes are received within that period,
the ESC code should be reported as an individual key press.

However, some systems (and I think that includes some IRIX systems)
seem to wait forever.

One possibility: you could try explicitly enabling the timeout, by
adding the line:

	notimeout(stdscr, FALSE);

to src/libes/vask/V_init.c.
