This is because the accents you enter manually are regular 8bit
characters. The ones from Stefano's document are tex-type accents like
\'{e} for é. The code that is broken on LyX/Mac is the drawing code
for these things.

OK, so this seems to be a height problem.

This may be just a drawing glitch. Isn't there another accent
appearing on the upper line when you do this?

Is it with 1.3.X or 1.4.x?
[later]
Bennett, can you try the attached patch (against 1.4.0cvs)? If it does
not work, could you show me what is the output on console? Here I get
something like
[...]
accent=` ascent=15 descent=-12 height=3
char=e ascent=10 descent=0 height=10
[...]
The first line shows a negative descent, meaning that the accent is a
very thin character that lives over the baseline. I suspect that it is
not the case on LyX/Mac, and the patch tries to catter for it.
