The function I wrote just returned Qnil/Qt based on popup_activated(), which
is non-zero if the menu-bar or a popup-menu is active.  That includes dialog
boxes.

In some ways it's a pity we can't (I assume we can't) shoehorn scroll-bar
activation into it too, since that would remove the necessity for the extra
conditions in mouse-autoselect-window-cancel.

I can't think of anything else to handle.  Simon.
