RH5 JavaHelp Remote URL to Web Form

I was wondering if anyone has encountered this issue.

In order to get around the JavaHelp limitations with forms, we have been linking via a remote URL to a web form (created in FrontPage) to collect feedback through email. The form is no longer working in JavaHelp. The page loads in the JavaHelp window, but it never goes anywhere. When you click submit, the form resets and nothing is received in email. The form works fine when linked on the web or in WebHelp.

I've tried a removing the link and reinserting, changing the recipient, the confirmation page, but no luck. Any suggestions? Other than switching to something other than JavaHelp -- 'fraid I've got no control over that decision
