Form posting is a real pain with the browser control. You can't capture any of the post data in the parameters of the BeforeNavigate2 event.

The only 2 options I can think of are:

1. If the asp page can be re-worked to accept GET vars rather than POST vars, try that.

2. Use something like Rick Strahl's wwIpStuff to handle all of the navigation to the pages internally, and dump the HTML to disk.

I got the same Navigational problems as you in my sample form...
