saveurl called not invoked in IE 6

saveurl called not invoked in IE 6

Hi,
I'm using the Remote API to Writer, and it's brilliant in Firefox 2.0.

However, in IE6 it doesn't work so well...

The request I'm sending (from cURL in PHP) should be identical - all the POST fields are the same between FF and IE - but the URL I give as the saveurl just isn't invoked in IE when I click on Save. Document Saved is not displayed.

Have you had problems like this before? Any suggestions on how I can debug it?

Thanks!
