Adobe Reader 8 and submitform

This is a mystery. I've done plenty of submit form actions that work across the board from Acrobat 5 to 8 without a problem. Has anyone else seen this on another system? Can you post this form somewhere we can look at it?

There may be something else going on here. Acrobat 8 has much greater security that previous versions. You should look at the security settings in the Acrobat Preferences.

Is there another action that's going on right before the submit that 8 might be objecting to? Acrobat 8 also display warning messages that allow the user to block web access. Could you have told Acrobat at some point to block this web site?

Hi Thom,
I have tried to change some of the security settings, but perhaps I don't know which ones to change.
You can see my form at [url=https://www.tastselv.skat.dk/diverse/eblanket/01004-030101.pdf]https://www.tastselv.skat.dk/diverse/eblanket/01004-030101.pdf[/url]
If the data 'Underskrift' is filled with just something, and you click the SEND-button, this javascript is executed:

function send_dokument()
{
var toUrl = this.getField("csc-urladr").value;
this.submitForm(toUrl,true,false,null,false,true,true,false,false,true,false,false,false);

this.getField("csc-dokstatus").value = 1; // blanktten er sendt
this.getField("sendknap").hidden=true; //skjul SEND knappen
this.getField("menuknap").hidden=false; //vis MENU knappen
this.getField("menuknap").setFocus();
this.getField("csc-kvittering").value=""; //blank kvitteringsdata
this.getField("csc-kvittering").hidden=false; //åbn kvitteringsfeltet
beskyt(); //skrivebeskyt alle felter (protect all fields)
}

PS. Neither Mozilla Firefox or IE works with AR v.8.x
Thanks in advance !
