thank you for responding. Actually, I wanted to know whether there is
some way to let rio behave as, say Windows Explorer or Firefox,
as in that particular website ('http://www.math-jobs.com')
or 'http://www.math-jobs.com/com/center', I get the same response
from rio as if I loaded it by lynx ('your browser doesn't support frames').
There is just no way to get past that message and to the version
of the website with frames, which I get when I load it in the traditional
way, clicking it in Mozilla 1.7.6.
Do you know how to enforce behaviour as of Firefox or Internet Explorer?
