Hello William.

Thanks, You do a great job running the forum btw.

I should have been more specific.

If I don't log in (using the browser) then all the pages in the site say I'm
not logged in. Obviously.

If I do log in (using the browser, and no special methods) then I get the vast
majority of the pages just fine using HTTrack or on another browser on the
same machine. So the website authentication doesn't use cookies.

However, any pages with a figure downloaded by HTTrack say I'm not logged in.

It's possible that the download just takes too long, and since the figures are
several clicks away from the page I'm starting at, HTTrack doesn't get there
before the website times out. But pausing and logging in periodically doesn't
seem to help. So I'm not sure what's going on.

Cheers
Hector
