Again with the start using.

>It seems the library stacks in question are listed as "Stacks in 
>Use".  Is this normal?

Yup.  When a "start using ..." statement is processed successfully, 
the library stack is added to the stacksInUse property.  The Message 
Box button, as you know, displays the contents of stacksInUse, which 
you can also reference by script:

   if someLibrary is not in the stacksInUse then answer error 
someLibrary&&"is unavailable!"
