I'm in the final stages of writing a PhD dissertation and the bibliography (works consulted) is single spacing. I've had an experience today when several lines at various places in the document decide to become what looks like 1.5 spacing. Nothing I do can get the single spacing again.

I have tried selecting the entire document and going to 1.5 and 2 spacing and then back to 1 spacing. Still no success.

What is causing a document to change line spacing for 5 lines in an ad hoc fashion? It has done this in 3 places within the 50 pages.

Changing the Show/hide icon hasn't helped.

Do any of you have ideas about how to fix it?

I'm using Word 2003
