Entire form not being displayed

I have created a form in Access to view/edit data from a table. When I open the form, though, only half of the form is being displayed and I have to scroll down to to get the rest of it to show up. It almost appears that there is an "invisible window" restricting how much of the form is being displayed. There is so much empty space at the bottom, i.e., beneath the "Senior Update" section that can be displayed. How can I make more of the form appear?  I would like to have at least a screenful of it to show up.
