[texworks] What file should TeXworks attempt to typeset when the green "Typeset" button is clicked in the preview window ?

No, this is not intended.
The intended behavior is for TeXworks to use an open file that typesets 
the given pdf. If several files are open that correspond to the given 
pdf (e.g., by means of a "!TeX root" statement), any one of those could 
be used. If no appropriate file is open, TeXworks should try to find and 
open one (this would likely be the root file).

Unfortunately, I could not reproduce the issue in my quick tests so far. 
Could you specify which files you created/opened/saved/typeset/closed in 
which order? Maybe even provide (minimal) example files to facilitate 
testing? It might be that something confuses TeXworks' internal map of 
which .tex window corresponds to which .pdf window, but this very likely 
depends on the exact order of operations.

All the best,
Stefan
