Over the past few days, I've been prompted to re-sign in to the forum several times. This only used to happen about once a week.

Has anyone else noticed similar behaviour? I'm wondering if there's been a change to the validity period of the authentication cookies that the forum uses, or if the change is at my end.

Not yet... I'd delete all cookies from IE and then relog in... sometimes you have an erroneous cookie and it will give you headaches.

Mmmmmm - cookies...

PLEASE , no food in the car !
