Hi Allen,

I'm running HTML::Prototype 1.36 and with this script:

#!/usr/bin/perl

use warnings;
use strict;
#Written by Kevin at Mon 12 Dec 2005 10:44:33 PM EST

use HTML::Prototype;

my $p = new HTML::Prototype;

print $p->link_to_remote('title',{
 update => 'a_node' ,
  url    => '/some.html'});

I get this result:

<a href="/some.html" onclick=" new Ajax.Updater( 'a_node', 
'/some.html', { asynchronous: 1 } ) ; return false">title</a>

I'm not sure if it's the upgrade with HTML::Prototype that did it. 
Here are a few suggestions:

1) Do a "locate Prototype.pm".  You should see something like below:

[kevin at localhost ~]$ locate Prototype.pm
/usr/lib/perl5/site_perl/5.8.6/Catalyst/Helper/Prototype.pm
/usr/lib/perl5/site_perl/5.8.6/Catalyst/Plugin/Prototype.pm
/usr/lib/perl5/site_perl/5.8.6/HTML/Prototype.pm

If there are more lines, you might have conflicting versions of HTML::Prototype.

2) It's very possible that the HTML escaping is being done by your
View (I'm assuming you're using Catalyst since you posted this here). 
If you're using Mason, check to make sure you don't have a <%filter>
that's overriding the result.

If you can, post more information about your setup and how you're
using the code.

Hope this helps,
Kevin
