Thanks for the work. A few random comments:
 * "Follow focus" should not be responsible, at it is designed to keep
the cursor/selection in the preview window sync'd to the cursor in the
editor window. It should not have anything to do with the menu.
 * Mixing Qt versions is probably not the best of ideas, but IMHO should
not cause any severe problems (assuming they are both installed
independently properly)
 * Window-related things (including menus and such) are typically out of
control of the end user code (i.e., the code of Tw). They are handled by
Qt (and on an even lower level by the window manager, of course).
