You do want to use layers though (OCGs). Different viewers will render the form field differently but layers will always look right.
Thanks for the response --- AND for not saying you're making it more difficult that it needs to be, lol.
Layers are completely new to me but I began experimenting with them last night. Will try more later on and respond back. Thanks much; more to follow!
Sorry delay; death in the family. =( Tell the people you love that you love them.
Thanks again to Joel_Geraci and gkaiseril for the comments. Those layers are pretty useful!
Since form fields render "on top" of the layers, and since Preview on Mac has issues with displaying form fields in their exact location, I was also going to set all my fields to hidden and then run a documents level script (thx gkaiseril!) to show all the hidden fields on open.
But there's a problem on DOC CLOSE. If the end user does NOT save changes before closing the file, then a script to re-set all fields back to hidden (in the close event) won't work, I think. Any way around this?
