maybe can be an idea, but don't know where work! I've read that a lot of people have the problem of page size. The maximum stage width is 1000 pxl, so u must have a page width max 500 pxl. If is larger than this cut the external border. It's possible to have a rollover area that move the page until the border, so could be readable page larger than 500 pxl?
ps: hope have explain enough clearly!!! (my english is a little bit old!
