Acrobat XI form editing - cannot drag a form field to edit tab order
I am working in Acrobat XI. I'm up to about 70 fields and have plenty to go.
Suddenly I cannot drag a field to change its order in the field pane. I click, hold and drag, and can see the little dotted line move, but when I unclick the field remains stuck. All of the fields appear to be locked against dragging.
I could find nothing in the discussions on this problem and would appreciate any help. Thank you.
EDIT: I should add - I do have "sort manually" checked under the Tab Order dropdown.
