Movie clips, layers and Actionscript

Hello Forum,

There is something I do not quite understand. I have a base flash 8 document.
I have a main timeline, and then I create 2 containers, each of which I attach a movie clip.
I use the createEmpymovieclip, and the attacheMovieClip for this process.

In one container I have a button (a movie clip really). My rollover and roll out work, but my onPress (or onRelease) action for the clip does not fire. I create the second container after the first container, and the button seems to be on the "highest" layer. What am I missing as far as the onRelease action for this button? Any ideas?

thanks,
