Go to Control Panels, Printers. Check the paper size. Setting the printer back to letter or legal page size should fix the problem.
There is an upper limit on the amount of inches (or pages) that Claris Works can support for a given document. With the page set to a small size, the word processor could not open a new document correctly.
Note: The word processor was the only module affected by the small page size. All other modules functioned properly.
