Other options instead of PDF forms...

The pdf form corruption problem via Preview is well known and documented. My forms couldn't be more simple. Just plain text boxes.

I am willing to try another pdf authoring option, but since we have used Acrobat Pro for so long, I honestly don't know who else to try. Any suggestions?

Yes and no.

One of the more prevalent issues that I have come across is if a form has a large text box (just simple text) that a tech has to fill in, which they do fill in and save then email back, it will show up as a blank field upon opening at this end. Then, if you click on the "empty" field, the text appears. But as soon as you move to a different area, the text disappears again making it impossible to print. That particular problem seems to only afflict the multi-line text box, not the single line.

Now, as far as the single line text boxes, there have been all sorts of strange issues. Some of which you can't even see until you print the document and then have what looks like double exposed areas of text.

I have an example of what that tends to look like. The crazy thing, you will have no idea there is anything out of whack until you hit print (to printer or pdf).
