When a visitor closes their browser, or stops the page from completing its loading, no message is sent to the server, so your PHP script won't know about it. The only way I know of currently to check for this is use some form of regular check-in, with Ajax or something, that calls home at regular intervals to inform your script that it is indeed still connected. If it fails to call home in time it either means there's lag on the connection or they broke it. Thanks, Ash http://www.ashleysheridan.co.uk
