Ah, good to know; maybe I can slim down my gtk-quartz package.

Just for the record, I now see what the problem was. Years ago 
I picked up from somewhere the idiom of testing for 
right-click by getting the GdkModifierType via 
gdk_window_get_pointer() on the GdkWindow associated with
the widget that emitted the button-press signal. In normal
use this is unnecessarily roundabout, since the 
GdkModifierType is right there in the "state" member of the
GdkEventButton, but I didn't notice a problem because the 
roundabout method works OK on X11 and Windows.

The idiom I was using doesn't work on gtk-quartz, but if I 
replace my old test with a simple examination of event->state, 
that works fine.
