My Light Controls window has disappeared. when the Pose room is open.  In the Materials room, the "Light Controls" title and controls are there, but they are nowhere to be seen in the Pose room.

Yes, I've toggled the "Light Controls", so please don't offer that answer-- off and on, off and on, several times.  No LIght Controls.  I'm not a noob-- I just can't find my light controls for some reason.  I've tried reseting to the factory state-- no luck.  I have no idea whay they are missing now either.  Is it something I've done?

Has anyone else ever had this problem?
