To the left of the word survey there should be four little icons. The one closest to the word survey is to take you into the survey mode. The number of images displayed in the survey mode depends on the number of images you have highlighted in the filmstrip. Just to clarify, is your toolbar displayed properly?
Added later: in the toolbar, the little down arrow at the right side of the toolbar, click on it and make sure there is a checkmark in view modes. I think that is what you are missing.
