I was amazed that Microsoft managed to introduce a bug into Notepad when they released Windows 2000 (and it's still there). Using CTRL_S to save your document can make Notepad think the line ends before it really does, and you need to bring the next line back up to fix the problem.... damned irritating for a keyboard commando like myself.
