Online Rating with Audio Files

[rob potter]

Hey there--
I'm trying to use the on-line rating function for rating audio files.
We've used it successfully with video files before.
But, when I simply replace what used to be the "movie" with a "sound file" in the line that follows the on-line ratings, it never ends the questionnaire. Just keeps the slider on the screen forever and (since the arrows are being used) I have to hard-reset my computer to get out of it.

Any ideas.
I've attached the .que file.
Thanks!
Rob
