Ok What do you suggest for putting a sound on a button?  I am working on the sound board on my computer and while adding the sounds to the buttons hit frame I chose to have the button "start" the sound as apposed to "stream" the sound.   Ok so what is the difference?  and when i chose to stream the sound it would not play on my computer.  I think it gave an error or something. idk the exact error because im at work right now.  But if I oublish it to the internet should the sound be streamed?
