Strange authentication request
 

While visiting one of my own mystical realm threads I got a dialogue box popping up saying

A user name and password are being requested by https://wwwc2.lshtm.ac.uk. The site says: "LSHTM Intranet Access"

It is asking for a user name and password - I have been closing it where I can

Anyone else with this problem?

What thread is it Sticks?

I have managed to suss the problem, what used to be a public image, now seems to be restricted to someone's Intranet

As a work around I removed the image linkl

Yeah thats actually happened a few times with linked images that have been posted although the other times it's been a virus warning not a popup asking for a password but at least you found out what was causing it.
