after some further debugging and guesswork, i am starting to think
that this program fails at the point when the querystring is being
passed
to the iframe object:

IFrameDoc.location.replace(URL);

has anybody out there had any problems with using location.replace()
as a way of passing the upload querystring through the iframe to the
server?
