A follow-up on my own post.
My compiled version of perfly source (for Performer
3.2.1) will work on the display described below if
you specify "-M6" and a command line option.
But..
It only works once in a while - about 1 chance
in 10. The other times it will show a blank
graphics screen or show the geometry/menu
with no mouse interaction. You need to kill
the program from another shell.
This is model depentant. Use "esprit.flt" and
it will sometimes work. Use "ch53.pfb" and
it never does.
