I have been creating a bunch of editable PDFs (PDF forms) using Acrobat 8 Professional. I simply created a PDF from a Word doc, and, using the Forms Toolbar, inserted text fields, checkboxes, etc - no problem.

When I open any of the PDF forms I created in the first round with Acrobat Reader, I get a purple bar along the top that allows me to toggle a "Highlight Fields" setting.

For some reason, PDF forms I now create no longer have that purple bar along the top. I don't recall changing any settings, but imagine I must have at some point.

Can anyone help?

How many text fields to you use?

Checl also the settings in the preferences of Adobe Reader.

I've tried creating new PDF forms with a single and multiple (3) text fields.

Also, I don't think it's a setting of Adobe Reader, as users see the purple bar for some PDFs, but not others - without changing settings ...

To get the purple bar you must have 3 or more fields.

Aha - thanks so much for the insight, Bernd. Appreciate it.
