I have a clip “msk” inside which I have two movie clips: “square1” and “square2”. Each of these two clips is assigned a mouse\_over listener so clips change their transparency on roll over.

Now I need to apply “msk” as a mask to another movie clip. When I do that my listener stops working.

Can anyone please suggest the best way of having the same functionality for clips inside “msk” so that I could mask some clip with “msk” and change transparency of “square1”, “square2” when someone rolls the mouse over them?
