If you were just trying to track if the message was displayed I would say use an IMG tag instead of the A tag, that would allow your web server to get the request each time the IMG tag is displayed without a web browser being opened. Of course this would not work if the email client is configured to not display images or receive in plain text. I don’t think the IMG tag approach would work properly for a 'click here to confirm/agree' button. I think you will need to link to an actual page using an A tag for that button to respond to a click event. You could include JavaScript in the HTML response that 4D sends back to close the window, For example, make sure that http://10.0.0.8:8080/confirm?539D36962A0A45478F0538EE894A4D5358CBB76FAED59F44B32DEEA97B22F3B4 returns HTML that runs window.close on load. But this will still open the web browser, and if the web browser has JavaScript disabled then the window would not close. -Tim ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **********************************************************************
