[support] Left nav is gone for some pages....

Hi Folks, I have a problem that is driving me crazy. On some pages, like ecf.jpg, I have my desired left nav. On some others, the left nav disappears like jury.jpg. I have no idea how to turn that on or off. Can someone give me a clue of where to look for this? Thanks, Phil(See attached file: ECF.jpg)(See attached file: jury.jpg)
