7.0.1 Loops Sounds on a Mac (whether you want to or not)

[Ray]

My Mac is running 10.7.1.  The script is just two lines:

on mouseUp
    wait until the sound is done
    play [wavFilePath]
end mouseUp

This works for the first click but a second click and the sound loops.  
This only shows up on a Mac.

The documentation regarding looping is kind of confusing.  It says it 
specifies whether a movie "or sound" loops, but looping is a property of 
a player, something not usually used when simply playing sound file.

Ideas?
