Symbol runtime sharing

Question

first time using runtime sharing, and i found that the
sharing symbol are not load when the swf start,
it only load the symbol(swf) when required by next frame.
my questions is:
1. is there any way to get notice that the shared
library(swf) are being loading (AS3.0)?
2. how the runtime sharing actually work? as the Flex
external link which load the swf into same ApplicationDomain?
thankyou very much

You know, the way these RSLs are set up is a joke.  If I paste a RSL object in my library, I get errors in "tempInit, line 7" saying it can't find the definition of the RSL object, unless I also go into the AS3 settings and add the RSL's SWC file as a RSL reference, then it compiles.  Unfortunately, that has the nasty side effect of altering the base-type of my movie, so instead of using my defined base class, it becomes some kind of RSL Preloader.  What a hack.  If I use an RSL, it should not modify the base type of the movie, it should be loaded transparently by the player before the loaded movie's COMPLETE event is fired.  The behavior of this thing makes no sense at all.  When I use a Loader to load the content, I'm getting random errors now saying "not enough information downloaded yet" for example, to get the width of the movie, however, the movie's Loader's COMPLETE event has already fired.
If I change the linkage on the RSL to be "external", then it will compile without the tempInit error, however, when the lesson loads, it completely wipes out everything in the player.  If I right click on the player, it actually says "No movie loaded..." in the right click menu.  What is going on?
