Actually, OnPlayerUpdate not being called doesn't tell you what the OP is asking. He is asking for detection if they are in the PAUSE MENU, - not if they are tabbed. How-ever, - they could plain out be tabbed outside of the menu. So, - in a direct answer, - as far as I know it's not detectable how-ever you can detect if they are AFK / Tabbed using OnPlayerUpdate.
