Can't clear notes for Creatures

OS: WINE
Version: 0.3.0

Go to creature menu

Add a note to a creature “ipsum”

Attempt to clear the note by editing the note and deleting everything (press ok)

“ipsum” still shows.

Editing notes and shortening or extending with new info updates the note.

You have to clear it by inputting only “!” without the quotes.

Nevermind, the text is just so small indicating what character I have to press to clear the notes (still don’t know what it is)

Thanks.
Why special case it though?

An obvious way to clear notes would be to delete everything.
Or, have a clear button.
