Using webform in a frame...

I have a Drupal site running in a frame, on this site I have a multipage webform...

For some strange reason you can't get to page 2 in the webform when using Microsoft Internet Explorer.

The page submits but stays on page 1, it works without a problem when running the site outside the frame.
But sadly I have to run it from the frame.

Maybe it could be something with the forms target, that IE doesn't get. How would I add the attribute target="_self" to my webform, not saying that it will work if i do that, but I would like to try....

AND COMPLETELY different thing, how do I redirect the user to a specific node when the user as submitted last page of the webform.
