Sorry to bring up an old topic, but if you use PN, I strongly recommend you update to the latest version. Just make sure you install it to the same directory as the devkitPro version, which is usually:
C:\devkitPro\Programmers Notepad
Do NOT uninstall the old version first.
TextUtil is also a great addon for PN.
