I didn't mean to imply that using Spacing Before/After would get rid of the lines, just that there would be fewer of them (no lines around empty paragraphs).
I actually use Word 2003 for most production work, Word 2010 when .dox/.dotx format is required. Both have their merits; there are many features I really like in Word 2010, but I'm still more comfortable (and efficient) in 2003. I have Word 2007 and 2013 installed only for reference in answering user questions.
