Whilst working away on a slew of CSS bug fixes at The Agency, Notepad++ wasn't. Or rather, didn't. Occasionally.
Two or three times a day, Notepad++ just froze, a blank white screen of nothingness. This highlighted the number 1 requirement of any tool, that it just works. Now I don't know why Notepad++ was freezing, and I don't have the time right at the moment to find out.
This ability to change software is one of the wonderful things about Free Open Source Software, you can do this so easily. No license numbers, time-limited demos, nag screens, nope, none of that. But I do feel bad, even though it's a matter of expediency, as I just need a text editor that works.
