  Good!

  This looks like an issue with fltk-1.3.

  FWIW,  inside  fltk-1.3  src/Fl_x.cxx:1443,  there's no code to
handle  those buttons. Having something like the following may be
worth a try (if you're a coder):

    if (xevent.xbutton.button == Button4) {
      Fl::e_dy = -1; // Up
      event = FL_MOUSEWHEEL;
    } else if (xevent.xbutton.button == Button5) {
      Fl::e_dy = +1; // Down
      event = FL_MOUSEWHEEL;
+   } else if (xevent.xbutton.button == Button6) {
+     Fl::e_dx = -1; // Left
+     event = FL_MOUSEWHEEL;
+   } else if (xevent.xbutton.button == Button7) {
+     Fl::e_dx = +1; // Right
+     event = FL_MOUSEWHEEL;
    } else {
      Fl::e_state |= (FL_BUTTON1 << (xevent.xbutton.button-1));
      event = FL_PUSH;
      checkdouble();
    }
