How interesting!

Since you were so helpful, let me try one more problem I've had. In some Word documents, created in Word 2013, there is something wrong with the F8 function. When i try to extend the selection over more than a page, the selection turns off; i.e., I cannot select more than a page.

I've discovered that if I save the document as a older version of a Word document, (97-2003), then the selection process works fine.

Any idea about how I can correct this without having to resort to this strange, inconvenient procedure?
