[pdftex] FORMS of hyperref only work with Acrobat Professional ??

[TW Ma]

I have done         testform.tex---->testform.pdf
with pdflatex by miktex on window-2000. 

When I click the text-field, I got an error message: Adobe Reader does not
save the data (see the end of this email). I tried to contact
Acrobat-Professional for advice but could not find the email address from
their site. Be very grateful if somebody could help before I decide to
purchase Acrobat-Professional.

Questions:

a) Should I use Acrobat-Professional to process testform.pdf ? 
Could version-5 do this job? Or must be version-6??
Is there any command in pdf-Latex similar to something like 

        \usepackage{acrobatProfessional}

b) Should the viewers (Clients) have a copy of acrobat-Professional instead
of the free copy of acrobatReader in order to send data to me? This is my
interpretation of the error message. In this case, the application of
pdf-forms would be very restrictive.

c) Hyperref has been around for many years. What is the easiest way to pass
data from   testform.pdf to the action-file: abcxyz.php?? Related pointers
to examples would also be greatly appreciated. 

Thank you in advance.   twma at maths.uwa.edu.au
