Apple Users Data Doesn't Show in PDF Form

Hello,

We created a form using Acrobat 9.  The form can be filled in and saved so people can email it back to us.

Whenever I receive a form from somebody that is using an Apple, the characters they have typed, don't show up in the boxes unless you click the box where the data should be.  It won't print the data either.

For example, let's say I have part of the form where people type a paragraph.  When they email the form over, it's blank....unless I click the box the data in is, they it shows up.  This only happens with Apples users.

Do you have any thoughts on why this is and how to correct it?

Thanks!

Dave
