That seems to be to do with auto-completion of entry boxes. That's not the problem for me. I'm quite happy that it won't auto-complete. I type my username and password (and never let any browser remember my passwords), and tick the 'remember me' button. I can log in, and I stay logged in for a while. But when I come back, I'm dumped out again. Doesn't matter whether I use the drop-down boxes, or the full-fat login page.
This doesn't happen on any other forums that have persistent logins. Most use a cookie of some kind, and UKC certainly used to use cookies.
Oh, that's a point; I need to go and check that I've enabled cookies... I'm sure I must have, as other, cookie-based persistent logins are persistent, but... [checked: 'accept cookies' enabled]
It obviously only does it for 'troublemakers'...
