wordpad: Number of preview pages to show when unzoomed is persistent. 

Either one or two pages may be shown in print preview when zoomed out.
This value is stored in the registry in native wordpad, and preserved
while opening and closing the print preview.  Zooming in will only show one
page, but the pages shown value must be saved because it will return to the
preview pages shown value after unzooming completely. If two pages should
be shown when there is only one page of text, then a second blank page is
shown.
