need help overlapping mc's

:smoov: Ok... As shown in the attached .fla, I have 2 movie clips: a green circle and a blue oval. I am moving the blue oval over the green circle. Is there a way I can make the blue oval only visible when it passes through the green circle? Kind of like a mask I mean, but without making the circle invisible.

I saved it in flash MX 2004 format, if that is a problem, please let me know, but the attached archive should solve your problem.

considering this is the flash mx forum, I have saved it in that format. Hope this helps.
