Unwanted double vertical spacing on my classified ad

[Chocky Chockster]

I'm writing a classified ad now, but my single newlines are being converted into doubles. I can't easily paste the source and output into the box due to the forum formatting that gets applied automatically but you should be able to see the problem from the screenshots.

Generated HTML

I don't want to place the advert until the spacing is fixed, because it looks silly with so much whitespace. Other ads seem OK.

I'm using Chrome 39 on Windows 7, if that helps.

First guess... Are you cut and pasting your text from Word? Might be causing the issue - try putting it through Notepad first and see if that clears it up.

Thanks for the suggestion, but I pasted from notepad in the first place. In fact, get the same issue even if I just enter

A
B
C
D

it comes out as

A

B

C

D
