I have discovered a way to put a wav file in html that will play on both netscape and Internet exp...Just use the embed code and make it so that the player is only 2 pixels in size. This will make it invisible and the true attribute will make it play automatically. An example is at one of my web sites (www.bargaintrain.com). You are welcome to copy the html source for the wav. It is at the bottom of the html when you view source. Just replace the name.wav with your name.wav
