I don't have the font family Consolas and the text looks skimpy in the Post editor box.
I used to have a piece of code in my theme's functions.php, which changed the font to something larger and clearer, but this doesn't work after upgrading to 3.3.
All I tried in the css folder in wp-admin didn't help either. I know it should be one of the
font-family:Consolas,Monaco,monospace;
but I couldn't find the culprit.
