Charles,

It's been quite some time since I last looked at this stuff. It's
fragile, chances are it depends on circumstances, and it may changes
between versions. Or maybe it's predictable and happens at IFD reading
time. I just don't remember. The only way to find out, is to
investigate the code.


Best regards,

Joris
