AET 03may06 my new favourite for Windows, very close after TextPad. Very customisable. Pity it's not available on Linux.
JAG 03-May-2006 - see also PSPad - my favorite freeware programmer's editor.
alove 03-May-2006 - I've been using Crimson Editor for a few years, very sweet program. It has highlighting for all the major programming languages & line numbering, very stable and quick to load. It's freeware. I use it for HTML too!
pn0 30-06-2009 - It's open source. Source code has been released and actually there is a version 3.72 available on http://www.emeraldeditor.com Don't be confused with the URL it's Crimson Editor. Code is available for checkout through SVN.
