[Chimera-users] Inactive atoms

Dear Chimera Users, My Chimera seems to display atoms and side chains in dimmed dark colour (picture below). I’ve tried to change the colour but they don’t work. I also can’t select any of the atoms/sidechains by mouse click+ctrl unless I pick select all from the select menu. I am using Chimera 1.10 version. Could you help me how I can change the settings perhaps? Best regards, Naza
