Malfunction or feature?

You might want to try a couple of things first: (1) reapply the latest firmware manually (see the firmware upgrade sticky thread at the top of the forum)–it can become corrupt over time; and (2) if that doesn’t work and you don’t mind losing the content on the player, reformat the player from its System settings (which will, among other things, erase the content (but not the firmware) on the player–that sometimes can fix odd issues. Good luck!
