Paragraph Spacing

A just found a new problem. Again. Each time I want to start a new line in WLW but no necessarily a new paragraph, my paragraph spacing is off.
It is off be 1.5 instead of .5. which is where I want it to be or at least just below the previous line. Apparently there is not much help with Microsoft support nor Blogger.
 

So I went to w3school.com.

This is without editing the html code.
