I created a job application using form fields in Word 2007. At first, I am able to enter text into the form fields. But in the middle of filling it out, all of a sudden, when I click on a form field and try to enter text, nothing happens. I discovered that when I save & close the document and reopen it, the form fields will start working again. But I have to do that about 10 times to complete the entire application! What is wrong here, and how can I correct it? Thanks!
