Hi avl. Interesting. These work for me as well. It's like this: The site I was referring to is a Scrabble site and you need to have an annual subscription to play there. Thus I could send you a link but you wouldn't get in. When you use all seven of your letters for one word a little file called hall.wav plays off and you hear applause. I don't really care about hearing the applause, that's not the point. The file is not played, instead Opera downloads it and they end up in my Download folder and pile up there. Safari, Firefox, Chrome, all just play the file. They don't download it. That's a bit of a clearer description of what is going on.
