    Hey you know what? I did go ahead and look more closely at the headers after your post and I had been using a non-URL-decoded value for a parameter called ctl00_ContentPlaceHolder1_ctl00_rcbusertype_ClientState. The encoded value was %7B%22logEntries%22%3A%5B%5D%2C%22value%22%3A%22Subscriber%22%2C%22text%22%3A%22Subscriber%22%2C%22enabled%22%3Atrue%7D and I used http://meyerweb.com/eric/tools/dencoder/ to decode it so now the following works: 
    
$mech->set_fields(
            'ctl00$ContentPlaceHolder1$ctl00$rcbusertype_Input' => "Su
+bscriber",
            'ctl00$ContentPlaceHolder1$ctl00$txtUserName'    => $un,
            'ctl00$ContentPlaceHolder1$ctl00$txtPassword'    => $pw,
            ctl00_ContentPlaceHolder1_ctl00_rcbusertype_ClientState =>
            '{"logEntries":[],"value":"Subscriber","text":"Subscriber"
+,"enabled":true}'
);

my $response = $mech->click_button(
                            name => 'ctl00$ContentPlaceHolder1$ctl00$L
+oginButton',
                            x=>26,
                            y=>10
);

    Yes, if you read my post again, I'm sure you'll see I used "live http headers," which is a Firefox extension that allows me to examine what POST data my browser sends.

      You will need to replicate all data you see in the HTTP Live Headers, at least as long as submitting the form fails otherwise. You should also include ctl00_ContentPlaceHolder1_ctl00_rcbusertype_ClientState in your request, and also the __EVENTTARGET and other fields that the form has. The Live HTTP Headers should show you all values submitted, and you should also send all those values unless you know better.

        Looks like we cross posted; just want to note that I've never had to even mention the __EVENTTARGET, __EVENTARGUMENT, OR __VIEWSTATE parameters in order to get my programs to work, in my limited experience.
