See the screenshot attached it's a working example for the "maxiBoton" that you can replicate to all other buttons.
When the mouse is not over the object you also want to make sure that the "click" animation is not playing, otherwise you are replacing it with the "Default" animation right away.
Also, you might want to check out that you can set a speed per frame which would allow you to not have several time the same frame repeating itself in the animation.
Why have twice the same frame when you can have a single frame and set its individual speed to twice as long ?
Thanks for the mention of my nickname in your credits, not to be picky but please be sure to fix the order of the "i" and the "y"
For the facebook issue, it doesn't ring a bell right now so be sure to use the search function in the Tutorials section and see if anything shows up.
Perhaps check also the "how do I" forum in case some topics might already deal with the issue as well.
