Perhaps the onload event is fired when all of the file has actually
arrived, rather than when it has been sufficiently processed for its
height to be known.  I will test shorter intervals; but, as I am
using it, the jumping is not annoying.  _At_present_, an inadequate
interval leaves the iframe short ...

Another problem occurred when the file in the self-adjusting frame
contained a self-adjusting frame.  That was easily avoided when I
noticed that the inner material did not need to be framed (certain
site "design" rationalisations have been done since that material
was originated); un-framing it meant that no frame would be
shorter than the size of <iframe></iframe>.

While writing the above, it occurred to me that it would be easy
to set the size of the infant iframe to the value of DefaultHeight
provided, and adjust it later if the right height becomes known.
Then, for readers whose browser window is a sensible number of em
units wide, jumping will be replaced by minor hopping.

Thanks.
