Unfortunately, this does not work for lists for me (where the problem arises in the first place).
I.e. I am able to modify my "Normal" style so as to not include the "Don't add space" bit in paragraphs. So when I open a new documents, and click on the paragraph dialog box, the option is no longer included. But as soon as I create a bullet list, the option reappears.
Could someone please tell me how to remove this annoying setting EVERYWHERE (and preferably banish it forever and ever), including in bullet lists?
