Possibly. I have a swf, lets call it header_control that
loads a header.swf. Its the header swf that does the major work. In
this swf after a number of frames have played, it does a few
attachMovies when behave fine locally. You can take a look at the
problem online at www.mountainmysteryschool.com. After the header
plays the animation, there are a number of hidden movies that when
you rollover then, they should appear (I have tweened the alpha
property).
