I've never seen this before, and I've searched the forums for an explanation and couldn't find anything similar.
I have an Acrobat form on which I built a layer of fields: text, number, calculation, radio button, and submit buttons. It was working great, and the Field nav panel listed all field names.
I pasted an image onto the form page, decided I didn't like it, then deleted the image.
Here's the strange part: All the fields I created are still on the page; however, they all have the same field name and generic text field type...including the radio buttons and the submit buttons. The Fields nav panel doesn't list anything: it's totally blank.
Other than recreating all the fields (it's only one page, so I'm out only about an hour's work), what else could I try? Have I inadvertently turned something on (or off)? I certainly don't want to be in this boat again if I can help it!
