Using FireFox from home or from work does cure many issues, like the # of lines visible in the sig block, controlling font size, and everything to do with Lists.
It also cured my inability to enter or see line-feed carriage-returns in my Blog.
However, Blog text entry acts like the line-spacing when I hit "Enter" is 1-and-a-half-lines. I guess the intent is to assure lots of white space between paragraphs.
The only way I've found to get single-spaced lines other than let them wrap-around as part of a paragraph, is to make the text into a list.
