Help a noob!

Normally for me the Content Manager would show a bunch of tabs besides Assets such as Installed and Missing Dependencies, but for some reason it's only showing Assets now. This happened after I changed the aspect ratio to 16:9, but I changed the aspect ratio back to 4:3 and it still only shows Assets. What do I do to make it show the other tabs? :confused: I am using Trainz 2009 by the way.
Right click on the top row and choose which fields you want to display. This is how it works in TS12, so I'm assuming it's the same in TS2009. It's been a while since I used that version.
