I believe putting a stack into use will only place the stack script in the hierarchy.
Objects, like buttons, will not be "seen".

Yet after they are in use, the objects they contain (images at least) can be
successfully referenced as button icons in other stacks that are open.

I'm having a problem with behaviors not being resolved in my application
stack.
I have two stack files, lets call them library.livecode and
application.livecode. The script of the main stack of library.livecode has
handlers that I use in application.livecode by issuing a "start using"
command.
library.livecode also contains a substack named Behaviors whose card has a
bunch of buttons whose scripts I want to use as behaviors in
application.livecode butthe "start using" command doesn't seem to make the
behaviors available to the controls in application.livecode, by which I mean
they act like they don't have a behavior defined.
I can fix this by setting the stackFiles of the main stack of
application.livecode to "Behaviors,<path to library.livecode>". I have to
reference the Behaviors substack, not the main stack of library.livecode for
this to work.
I guess I'm wondering if this is the appropriate way to deal with this
situation or if there's a cleaner way to do it.
You're right - putting a stack into use doesn't load it into memory (e.g. it's
not in the mainstacks), so the behaviors go unresolved. Here's two ways to do it
(other than the one you described):
1) Open the library invisibly (I do this by trapping "on libraryStack":
on libraryStack
if the target is me then
open inv stack (the short name of me)
end if
end libraryStack
2) The "datagrid" trick - if you use "there is a stack" then it loads a stack
into memory but doesn't actually open it:
get (there is a stack<pathToStack>)
