Well, fools rush in where angels fear to tread... assuming my project manager
thinks we should.
I see now. I was looking in the wrong place. It's this piece I need to focus on:
AP: (1)
-<> N: (7) [47 0 R] /T:XObject /S:Form
+[]BBox: (4)
84 FormType: 1
84 Length: 148
+[]Matrix: (6)
+<>Resources: (2)
/ Subtype: Form
/ Type: Xobject
Here's an image showing the two files in PDFDebugger side by side:
http://aapro.net/PDF/Image1.jpg
In case anyone else wants to make sense of this... that file may not be there
in a few months though.

Yeah I know this effect when you do that.

Yes indeed. For some of the field types where we don't have an appearance
stream you may have weird effects.

Like I said... it's tricky. If you know the sizes of your fields, i.e.
that these stay the same, you can open the file with Adobe Reader, save, open
with PDFDebugger and then copy the structure / contents.
