WebBrowser1 opening new window on form submit

Hello,

I'm using the WebBrowser object within Excel to automate a task. I can use it to populate a form, but when it clicks Submit, it opens in a new window and losses the session information. Is there a way to either copy the session information across to the new window, or to force the results to appear within my WebBrowser object? Any help would be much appreciated.

Thanks.
Andrew.
