Bass,
This is what I do to solve the problem you describe. In the document, show the paragraph marks.
1) Make sure there are no extraneous lines leaking onto the new page.
2) At the end of the page with the text, after the last character, ensure you have a least one blank space BEFORE the page break.
3) If two fails, I will shorten a sentence on the page, to ensure a one space AND a newline BEFORE the page break.
These steps have worked for me, your mileage may vary.

UPDATE
This just happened to me, in a WIP that came back from the editor, the above process worked with a catch.
To correct the pagination error, I had to TURN OFF Track Changes.
