See, that's the way I thought that panel worked at first as well
-- but it's not :)
The Input panel on the left *shows* you what portion of the input
has been successfully parsed thus far. It's not where you enter
the input itself.
When you start debugging a separate dialog is supposed to pop up
with a big input field for the actual input data. I've seen it a
few times, but then I've also had it *not* pop up a few times as
well. I haven't played with debugging in AW enough to know what
makes it appear, and whether this is a bug or not.
