Hi there,
Recently I’ve decided to change the font I was using in my editor ( flashdevelop ), for a better one. So I’ve looked around on the web to find which free programming fonts ( monospace font ) I could use and I’ve found TOO MANY of them 
I didn’t look at all of them but end up using the ProggyClean font ( http://www.proggyfonts.com/ ). Really neat font to code with.
I’ve found too a font that “looks” good but once installed on my computer and using it with flashdevelop, the font was blurry. I dunno if it’s coming from flashdevelop ( probably ). I’ll email the guy
The font is the Envy Code R by Damien Guard and you can find it HERE
I would be interested to see, in the comments, which font you are using in your favorite editor. Maybe I miss THE one.
