I recently designed a form to be filled out and submitted to Form Central. It seems to work fine when the respondent is using a DOS based system. However, it does not appear to work when the respondent is using an Apple product. They are able to open the form or view it in the body of the email but: 1) the boxes to fill in or make a selection are not visible; 2) they cannot click and move to a position anywhere within the form; and 3) the "submit" button is not visible. The form is being distributed as an attachment to an email.
