What you describe sounds as though it should work.  Some reasons it 
might not:

  - You have an error in the new material.  This would normally be 
indicated at the bottom of the *.tex screen by a console message and 
some messages under the "Errors, warnings, badboxes" tab.  I believe you 
usually get an updated display if there's nothing worse than a warning, 
but errors stop the process and need to be fixed.  A successful run will 
have something like this at the end:

   Output written on main.pdf (251 pages, 2976685 bytes).
   SyncTeX written on main.synctex.gz.
   Transcript written on main.log.

  - On Windows (and other platforms?), I think your PDF file is locked 
by some viewers, so you can't update it until you close them.  I don't 
think this happens if you're only using the internal TeXWorks viewer, 
but I seem to recall that Acrobat Reader would lock it.

If neither of those is the issue, I think you'll need to give us more
