Webbrowser and modal dialog boxes

: Hi, I'm using TWebbrowser to access a intranet site so I can automate a web application. My problem is that after entering in some data and activating the submit button, the app then displays a confirmation modal dialog box asking if I want to continue, to which the possible answers are Yes or No. Of course my Delphi app halts until the dialog box has been closed. I am unable to make any change to the way the web app functions. My quesiton is, how am I able to control this dialog box and select Yes when my program is effectively halt due to the modal dialog box?
