NOTE: Fixed the problem.
I changed the line-height here and it worked:
.narrowcolumn .entry, .widecolumn .entry {
line-height: 1.4em;
}
I need to also increase the line space (leading) and this should be easy enough to fix, but for some reason it’s not working for me. I adjusted the line above as instructed to wp-content > themes > default > style.css but it’s not making a difference. Am I making the changes to the wrong style sheet?!? *~*
