Using Flash was indeed my first thought. However, this is an Intranet application. And although there are a lot of different system configurations (macs, windows and linux workstations all doing different things), the one common factor is that the system administrators have disallowed Flash and Java (browser plug-ins) on all machines (my second thought was to use a Java applet to handle this). I suppose this is to prevent the employees from going online and playing Flash/Shockwave or Java games, and YouTube (and similar) usage. Trying to block all those websites in the firewalls is an immense task, and disabling the flash player is the simplest solution for that. Anyway, that left me with the EMBED solution. I decided to take ppk's advice, and go with dropping new EMBED tags into the document when a sound effect is needed. This does mean that the browser will only start loading the plug-in when the sound effect should start playing, so there is a delay, but it works. On my testing machine, QuickTime is used to play WAV files, and the delay is hardly noticeable. Thanks for responding! Rick.
