i think im just doing something wrong or missing something easy but i just got this and i was on the tutorial for making a level and in the, First Room III part it tells you to build your level and it shows a picture of a menu that i dont get and it tells you to select the fly-thru option....the only problem is when I click on the build level button i dont get the same menu

ANY HELP WOULD B AWESOME!!!!!

THANX!
