WinampCOM problem

Hiya, Just wondering if anyone else is having this problem. I am trying to control Winamp through HTTP using the WinampCOM plugin. It works fine when I call the script from the command line but not at all when the exact same script runs through HTTP (using Apache). Here is a bit of the code I use:

        $Winamp = new COM("WinampCOM.Application") or die('Could not instanciate the WinampCOM object');

        if (isset($Winamp))
                echo 'Test: ' . $Winamp->CurrentSongFileName();

        else
                echo 'Not working';

Now, through the command line I see 'Test: ' followed by the current song's name but on the web page I see only 'Test: '. Anyone ever experienced this? Any help appreciated. For those who wonder, WinampCOM is available at: http://www.adcock8.freeserve.co.uk/winamp.htm. Thanks, Olivier
