The problem is that I make a text field in Acrobat Prof with the specs:
General: form field visible
Appearance: No border color. No field color. Font size 8 Courier.
Options: Multi-line checked + 600 chracters

My goal is to offer the form filler to supply 8 lines.

When I check if the text field works (on PC and Mac). On my systems I can type 8 lines.

When my customer tries it he can only submit 7 lines.

I have enlarged the text field box and still the customer can only submit 7 lines!
What �worked� is to specify in the tab Appearance Auto. But then there is no alignment with the question keywords and therefor not accepted by the customer.
I have even decreased the font size so I could get in 9 lines. But still he can get in only 7 lines.

So when I type:
1
2
3
4
5
6
7
8

The customer can only get this:
1
2
3
4
5
6
7

Has any one an idea? What is going on?

Every thing else is working fine: hiding fields etc, pop-ups are working fine, print function (script) works fine.

Thanks
