Whats wrong with my buttons!

Whats wrong with my buttons? here http://hiddenbrookstudio.com/index.swf, see how they rollover and dissappear and takes a second for them to reappear they should look like this http://www.hiddenbrookstudio.com/popup.html . Not counting the last button what did I do wrong here? I am modifying code of a programmer who is not with my company anymore and I need to edit this for a client

Seems as though that all but your last buttons are missing an applied tween + color transform to them. Mind you that's just a guess. Since the last button still operates as intended, why not see what the difference in code is between that and the rest of the non-working buttons.
