Hmm, I should have read the doc more closely before I replied.  My fault.

I doesn't work quite that automatically.  TrackPopupMenu is a
general-purpose Windows API -- it doesn't have any connection to or
knowledge of Windows Explorer, so it cannot force Explorer to take
actions.  If you don't specify TPM_RETURNCMD, then the final result of
selecting a menu item will be that a WM_COMMAND message sent to your
window.  Your window doesn't know what to do with those command codes,
so nothing useful will happen.  In this particular case, I think you
HAVE to use TPM_RETURNCMD.
