I have set up forms in a pdf document, then enabled "extend features in adobe reader" and saved the document. Now I see that there is a minor spelling mistake in the document and I want to correct it using the touch up text tool. But Acrobat won't let me. Can someone please tell me how to turn off whatever is stopping me from editing the document. I can't find any way to turn off the "extend features" option, which I assume is the culprit.
I'm using Acrobat 9 Pro, version 9.4.1, Windows 7 64.
