Losing Paragraphs in cruisersforum Style

[Captain Bill]

I recently changed my display style from vbulletin default to cruisersforum style. Since then paragraph breaks that I put in my posts are deleted when I submit. I edit my posts and put the paragraph breaks back in and when I repost they are gone again. I am placing a paragraph break at the end of this sentence.I suspect that the paragraph break immediately before this sentence will be gone when I post. Do I have a setting on my browser that is incompatible with the cruisersforum style? Also I tried to change back to the default, but it does not accept the change.
