I've found a bug in 3.7 I'm trying to find a work around.

First, Create a button.
Then move down to the Button States and Click on any one of the other tabs. In my case, Mouse Over.

Here is the error that pops up.

"Expression could not be evaluated on line 0 "

It closes and at first doesn't look to be a problem. However, when you export the movie the sound that you applied to the mouse over does not work. I've tryied to do it another way, by performing an action and that still doesn't work. W

What is funny is that the sound or actions that you applied will say they're there and will operate perfectly inside 3DFA's browser but do not export.

If anyone finds a fix let the board know.
