Actually, any text that's added to a button with ProntoEdit (rather than being part of the graphic) is not showing up. I've only seen it with a couple of CCFs so far, so I'll have to check it out further.

Sean,

The conversion tool is just another window in MXEditor. Even if all you had was a hex code, you could assign it to a button in ProntoEdit, then open that CCF in MXEditor. Granted it's an extra step, but easy to do when you're only talking about a few commands.
