interesting behavior. If you rollout of the mouse by going to the right (horizontally only), they all rollout fine. If you go up or down, they don’t. I have no idea what is wrong. Do you have enough space between buttons? Any other code underneath?
I´ve had the same problem. What I did was to create the animation for the rollout behavior an put that in the “up” frame off the button and I made the animation for the rollover effect and put that in the “over” frame of the button. That should work out just fine. The only problem is that the buttons animates when loaded, but that shouldn’t be too big of a problem!
