There was a _long_ pause at step 8; about 2 minutes ... and that is the
source of the apparent problem. I tried http://grass.osgeo.org/ then went
off to do something else. When I returned about 4 minutes later the page was
displayed.
Ergo, it will load, but there's time to make coffee before it does. This
changes the focus to where the delay for this one site might be.
Thanks, Robert and everyone else,
Rich
