Thanks fixed.

Thanks, all credit goes to Carsten for making Org-mode so much fun to

I'm sure there are still some bugs.  I definitely want to introduce this
more as "something that may be fun" rather than "supported software".

I'll take a look, I don't think I ever tested with an image (aside from
the LaTeX preview image).

This is one of those things that I don't think I'll ever really want to
implement as it begins to go beyond the complexity of what I consider a
simple tool.

My guess is that widening and narrowing the buffer is re-setting the
"edited" state of the buffer, but I can't say for sure.

Yea, epresent hides the cursor and the echo area, which makes any sort
of editing or navigation aside form using the built in functions a pain.
Maybe if scroll was bound to space-bar this could be fixed.

When does this happen?
