OK, maybe my setup is weird. :)

Can't say I'm too fond of the Ahem font. I try to avoid it when writing
tests. I guess I've seen too many Ahem tests with expectations that not
all font engines can live up to (like now). In my pessimistic mind, an
Ahem rendering can only be compared with another Ahem rendering, and not
with images, filled squares, etc. I usually end up using (inline-)blocks
with a background instead, or if I really have to use text, I just use
the default font, since I don't expect to be able to assume anything
about how Ahem text is going to be rendered (or even laid out), anyway.

BTW, on the computer I use now (Ubuntu something), Presto displays an
ugly half pixel wide vertical stripe between the characters in your
test. There are so many ways to "fail". :)

I don't think I've changed anything. I don't have access to that
computer right now, so I can't tell you more. I was running Windows 7
with IE10 inside a VirtualBox that runs under Debian. That might be a
clue, I suppose.

I could check.

I could try that as well.
