Interesting, will have to try that for you.

I've been seeing the exact same behaviour, have to log in nearly every time I visit.

I’ve had the same but I use it infrequently - so I thought maybe it required a new log in after a period of inactivity. It certainly is annoying having to log in again, regardless of the reason.

Absolutely hate this service for this exact reason...every time I try to use it I have to go through the process to log in....argh
