+    // if the X server _doesn't_ use it for NumLock).  So the old code caused
+    // wxKeyEvent::MetaDown() to always return true as long as NumLock was on
+    // on many systems, which broke all applications using
+    // wxKeyEvent::GetModifiers() to check modifiers state (see e.g.  here:

    Cursors, too, have been a constant source of pleasure. The main difficulty

-   and ending with the youngest generation (speaking of parent and child windows).

    Also don't forget that cursors (like much else) are connected to GdkWindows,
    not GtkWidgets and that the "window" field of a GtkWidget might very well
    point to the GdkWindow of the parent widget (-> "window-less widget") and
    that the two obviously have very different meanings.
