[OS X TeX] 2 questions on presentations

[Bruce Kellogg]

1. I use the seminar \documentclass, with the first several lines as  
follows:

\documentclass{seminar}
\usepackage{hyperref}
%\slideframe{plain}
\usepackage[metapost]{mfpic}
\usepackage[dvipsnames]{color}
\usepackage{amssymb}
\usepackage{amsmath}
\usepackage{amsthm}

I process the file and get some pages of output. Then I uncomment
'\slideframe{plain}', process the file and get the same output.  
Shouldn't
I get something different, such as each page having a frame around it?

2. I would like to try prosper. According to Kopka & Daly I must  
reset some stuff
in preferences to enable prosper. I confess to not knowing what to set.
Do i change something in the Engine pane, or the Misc pane, or the
Typesetting pane? At present, in the Misc pane I have mptopdf and  
Ghostscript
checked. In the Typesetting pane I have Pdftex checked.

I knew that my eyes were different,
one was myopic. The other, normal,
later became presbyotic. ... I wonder
if my peculiar eyesight, in addition to
affecting my reading habits, may also
have affected my habits of thought.
