I also have a new stubborn problem.
I recently replaced my old Pentium 4 Windows 7 desktop for a newer Windows 8.1 and have installed Office 2013.
Word and Excel are the workhorses for me.
There seems to be an endemic long-standing flaw(?) in Word, including Word 2013 that creates a blank page on a one page document that is like a vampire. Can't kill it.
I've tried every solution I can find on line without success. Any Freeper ideas? It's not a huge problem, just a constant irritation.
Any ideas would be welcome.
I have not ventured into Word 2013 so this is just a stab:
Try viewing the document in Outline format (View tab:Outline under “Views”) this should reveal all of the markup items and show you if a “New Page” control mark is inserted.
