The only difference is the mapsize; 200x120 on the first call, and 470 x 250 on the second.  The first call is on the site index page, hyperlinked to the second page, so the first will always be displayed first.  I'm also getting the error "loadForm(): Web application error. Not enough arguments for mapsize.", although the url calls the exact same .map file the only difference is the size.
