Acrobat 8 and Groupwise 7; Submitting form to multiple recipients.

I am having a problem e-mailing a PDF using a submit button. Specifically, I am running into problems when I attempt to send the form to multiple recipients. I am using Acrobat Pro 8.0 and my mail client is Groupwise 7.0.

I have an interactive form that contains a submit button. I set the submit button to execute the following URL:

mailto:address1 [at] address [dot] com

And everything works great. Then I tried added another recipient to the URL, something like:

mailto:address1 [at] address [dot] com;address2 [at] address [dot] com

The e-mail message still pops up, but only has the first the address (address1 [at] address [dot] com) in the TO field. The second address is ignored.

So then I tried adding the second e-mail address in the CC field, so I changed the URL to:

mailto:address1 [at] address [dot] com?cc=address2 [at] address [dot] com

Then it get's really wierd. It opens a new e-mail window, but both the To field and CC field are addressed to address1 [at] address [dot] com. It seems like no matter what I do, the message will only be addressed to one recipient.

I even tried abandoning the sumbit button completely, and tried the Javascript route. I tried both:

this.mailDoc(false, "address1 [at] address [dot] com;address2 [at] address [dot] com", "", "", "This is the subject", "This is the body.");

and:

this.mailDoc(false, "address1 [at] address [dot] com", "address2 [at] address [dot] com", "", "This is the subject", "This is the body.");

And I get the exact same behavior. If I specify two addresses for the To field, Groupwise uses the first address and ignores the second. If I specify one address for the To field and a different address for the CC field, Groupwise populates both the To and CC fields with the address I specified for the To field.

Help!
