I leave several browser tabs open on different pages of the WCG site. An hour or a day later I come back and hit refresh, or scroll backwards or forwards to review the adjacent pages I previously selected. If I have to log in again the sequence is broken (and it's wasting my time just to press enter to log on, or to re-enter options for forward pages which have been overwritten by the logon page). It's just a pain from a usability point of view. I feel like I'm having my wrist slapped for daring to use the site at all.

Thanks, Kevin. I hadn't noticed that the box was no longer checked, and I've no idea how that happened. I'll put it down to a browser hiccough, and apologise for bothering you.
