Does Debugger report progress of externally loaded SWFs?

I posted a longer version of this question previously without success to reply. I thought I would try again with a shortened version:

I am using Flash MX’s Debugger to test preloading from a main Flash file that loads externally loaded movies. It appears that it will demonstrate all the progress load time of the main Flash file, but not of the externally loaded movie.

Is this supposed to happen?

Thanks,
Marc
