i use notepad++ much for my personal editing.
I have tried many, but like this one most out of used ones. I also noticed a few editors on new site, have look http://codango.com/php/dir/software/develope/codeedit/?tab=refined.
I very much like http://www.codango.com/ for finding scripts and such I need. some other directories may also have some good lists of editors for you to read more on.
I hope you will find a lightweight editor that is much better and easier to use than dreamweaver. i wish you good of luck.
