If you look on the standard toolbar in 2003, or the 'Home' tab in 2007 you will find a button that looks like a funny backwards P (the symbol used for the Paragraph Marker) - If you hover the mouse over it, the label 'Show/Hide' should appear (SHORTCUT - Ctrl+*). This will allow you to see all the hidden markers in your document - With this, you can see if there are any of these markers on the extra page at the end; you can then decide what it is that you need to do to lose this page: i.e. delete any extras, decrease margin size, shrink tables, resize final paragraph marker.
