Button Freeze

Hi guys

I have made buttons that contain a MC with both rollover and rollout states.

All seems to be working fine except for when the mouse is moved over the buttons in a hurry and it almost seems to freeze all buttons in their “rollover” state.

Anyone have any ideas on how to make it run a little smoother?

Thanks for your help

Would someone mind elaborating? Ive been trying to make it alittle smoother but it doesnt seems to be working
