PDF page display truncated

OS Win 8.0 Scrivener

After importing more than 100 PDF files without problems, suddenly my newly imported PDF files are displaying in Scrivener with the bottom inch or so of the page truncated. Scrolling doesn’t help. Zoom makes no difference. PDF page display options (actual v. fit) makes no difference. PDF display options in the footer don’t help. Multipage PDFs have each page truncated the same way. Changing page setup in the File menu makes no difference. When switching the view to an external editor (Adobe) the page displays in full and correctly.
I’ve restarted Scrivener and rebooted the machine without improvement.
What in heaven’s name could be wrong?

AAAhh!~ The beta fixed it! Life can resume. :slight_smile:
