Auto login - keeps losing setting

[#1]

I keep finding that Auto Login on the Member Centre fails and I have to set it up again. I haven't logged out, accessed the Member Centre from another browser or from another PC. I suspect it may be due to the Tuesday rollouts of Plusnet portal updates. If this is the case shouldn't the the Service Status notifications have something to that effect in the Is there anything else I need to know? section?
Edit: It's a year since I moaned about this and ran a poll (the consensus was that a chocolate fireguard was more useful): http://community.plus.net/forum/index.php/topic,93852

Mine doesn't fail, but whenever I check the webpage as part of my general PlusNet trawl, it always states I am not auto logged in !!
I re-enable it just in case going to the webpage disables it.
