OK. So then maybe I need to understand a couple (LOL) things better.

First, are a background group's scripts available in a preOpenCard  
message if the background exists on the card that is being entered?

And second - that means that the message path is -
frontscripts->object->group->card->stacks->libraryStacks->backscripts

when there are no backgrounds. And,
frontscripts->object->group->card->backgrounds->stacks->libraryStacks- 
 >backscripts

if there is a background.

But what is the message path for objects within the backgrounded group?

Thanks for clarifying. It seems to me that a grasp of all the  
intricacies of the message path is one of the keys to optimal program  
operation, so I want to get this right.
