Well this has been going for ages but finally got to me!
I have set "Store my user name in a cookie for 1 year" to yes. But for some reason after a while (an hour maybe), I am no longer logged in and I have relog in.
I've tried setting it to NO, save, set it to YES and save it. I've tried removing the cookie as well and then doing the above.
Any other thoughts? I'm using IE6.
Thanks for suggestions.
