Plus sign appears in some Adobe scroll long text fields, not others

[Megan249324891gtz]

I have multiple text fields with identical properties in an Adobe Acrobat form.  All have been set to "Scroll Long Text".  The problem is that some text fields show a plus sign in the lower right hand corner to indicate the length of the text entered by the user exceeds the field's visibility; however, other text fields don't display the plus sign, so you can't tell that the field contains more text than is visible.  Why does this discrepancy exist if all text fields' properties are identical?  How do I get the plus sign to appear for all text fields with the "Scroll Long Text" property enabled?

Can you share (part of) this form?

Hi JR, I appreciate the quick reply!  To share the form, do I attach the file to my reply, or is there a different interface that I should use?  (I want to make sure I don't do something that would go against the community guidelines, since I'm still not up to speed on the protocol for document sharing.)

As you like.

Hi JR, my sincere apologies!  I don't know why I didn't get notification of your reply last August.  I was so fed up with my form that I gave up hope of trying to find a fix.  Then, just tonight, I ended up finding out the solution, totally by chance:  in Prepare Form view, I dragged the edge of one of the text fields to the side, making it larger; then, when I went to Edit --> Undo, the + sign was magically showing!  I have no idea why resizing a form text field and then undoing the resize would make the + sign appear, but that seems to be the fix.  I wanted to return to this original post so that if anyone else runs into the same problem, they'll know what to do.  I very much appreciate your help.  🙂  Thank you, JR!
