I was having an issue with NotePad bogging down while viewing my scripts (which are of the recorded type, so they're huge). As such, I did a brief search on google for some text editors, and found a great free source program called Notepad++. The files open immediately, and you can have more then one file opened (within a tab-like setup, think Firefox), and it organizes and spaces the code, too. I've found it very helpful. Here's the link to download it: http://notepad-plus-plus.org/download/v5.9.2.html
Nothing is easy to the unwilling.
