Hey, thanks! Can't believe I haven't seen that in all this time. Though, there are a lot of changes in your files' xml for just adding the letter 'x', and that cell is now a code cell that isn't rendered.
Do you mind if I just add the 'x' without changing any of the rest of the xml in the file?

Thanks,
Tom

Hmmmm.....not sure how that got messed up so bad. I should have just fixed it in a text editor. Yes, feel free just to make the change.

Ok, cool, done. Yeah, I edited my version and saved it only to see 1000 diffs. Had to revert and use vi so it only changed the one byte. Easy to not have that save exactly as you expect. It's fixed now.
Thanks for correcting this!
Tom
