Copy & Paste Message Box

You can copy & paste from a message box!

I've only just found out that in Windows XP you can hit Ctrl+C on a message box to copy that text to the clipboard. It must have been possible to do this for years and I never knew! I wish I'd been told about this before! It's going to massively useful, and it means I don't have to keep hunting around for CopyText when I want to do the same thing on some random PC.
