Client pls

How is it that live client is more buggy than PBE client? I keep ticking the "Stay signed in" box, and every day I have to type all my login info all over again, pointlessly ticking that same pointless option thinking it's gonna change. This hasnt happened on the PBE to me ever since the new client was put to test there. This has been going on for about two weeks in my case. Remove that goddamn option or make it actually work, please.
