Smurth, take a look at MY first reply :P

I suppose I can explain my results a little further than "doesn't work" though ;)

If I try your proposed solution, the tray loads outside the box and doesn't get hooked because the box has already been created. Then litestep crashes. Then I cry ;)

What I need is a way to hook the tray into the already-created box *after* the !NetReloadModule is called.
