In my User CP (and thus probably everyones) when you go to the Options and look at Browse board with cookies: it is set to OFF. I change it and then submit the form. When I go back into the Options, it is set to NO again.

Why would this be happening?

I don't see a hidden field for "nosessionhash" in the modifyoptions template.

hmmmmmm. anyone know what could be going on?
