Buttom mc problem with rollOver effect

Hi guys,

I’d like to ask for small help from anyone who can share their thoughts with with my problem with dynamic mc buttons. sometimes when i jerk my mouse over the mc buttons or if i hover on them very quick, they constantly flicker which doesnt seem right. i tried fixating diff mouse over events but no success unfortunately. i have attached the fla file so you can see the code and see what i mean.

I would gladly accept anyone’s opinion to solve the flickering problem.

Thanks y’all!
