Acrobat crashes when I try to read forms

Question

I created an intake form for my clients to complete on their computers and email back to me. Two have completed the forms and sent the back to me - but the text runs off the page as one long sentence rather than wrapping inside the text boxes I inserted. When I click on the + sign to expand the boxes and read the full responses, the document crashes and closes.
Acrobat XI Pro for Mac
Original document created in Word, turned into a PDF, text boxes inserted into the document, saved as a PDF, emailed to the clients.
I tested the text fields before I sent them, and they seemed to work just fine on my computer. Don't know what the problem is. Its the weekend, tech support is closed, and I need to read one of these documents by tomorrow.
Anyone know what's going on?

Answer 1

I figured it out. If anyone else has this problem, here's what you do:
When you first create a fillable form text box, you need to right click the box, click on PROPERTIES and select MULTI-LINE instead of SCROLL LONG TEXT. If your document has not been signed, you can go back and edit each fillable form text box so you can read the text.
Open the document
Click on TOOLS at the top of the page - this opens up a menu.
Click on FORMS, then EDIT. Now you can right-click in whichever box you need to adjust
Click on PROPERTIES, select OPTIONS
Check the box next to MULTI-LINE and uncheck SCROLL LONG TEXT
Repeat for whichever fillable text boxes need to be adjusted
Save the document
You're done
If your document has been signed, you can't alter it. You have to go into each text box, copy the text by highlighting it all, and paste it into another document so you can read it all.
Hope this helps someone.
