Compile as rtf - line spacing

When I compile in rtf (leaving all options as standard) and open the result in Word I’m having a lot of problems with line breaks being missing. In Scrivener there are lines between paragraphs but none in the compiled version. I’m having to add up to three carriage returns in order to get the paragraphs not to show up as one monolithic block. But even then the result is variable with sometimes an extra line between the paragraphs.

XP sp 3 Scrivener 1.5

I forgot to mention that I used rtf after using .txt and having as a result one monumental block of text with no carriage returns at all.
