Do you mean a way to bypass the weekly logout, or do some browsers logout every time unless you have a setting to stay logged in?
I don't think I've ever had to log in weekly, unless you mean if you don't come on for a week it would log you out, which sort of makes sense. I'd imagine AG updates the expiration date every time you're logged into the site, but after the expiration date it would automatically log you out (or rather, not have you logged in). It could be that whatever browser you are using isn't updating your cookies, if you still have to log in weekly regardless of when you get on.
Could be wrong, though.
