I want to have all of my menu windows "inside" of the main window. I don't want
to have each menu window appearing in the taskbar and I don't really need the
whole window decoration (max./min./close buttons).

As I mentioned, each of my subwindows is created as an object of a specific
class. The class constructor calls the "end()" method after adding all the
widgets.
The only window without an "end()" call was MainWin. I've now rewritten the
code to look like this:
// Globals
Fl_Double_Window* MainWin;
FwdKinematics* FKMenu;
FKMenuDH* FKPopDH;
..
FLGLWindow* GL_MainWin;
// Definition (inside main)
FKMenu = new FwdKinematics((int)(ScreenWidth*.12),
(int)(ScreenHeight*.12));
FKPopDH = new FKMenuDH(0,0);
...
GL_MainWin = new FLGLWindow(0, 20, ScreenWidth-6, ScreenHeight-44,
"Robotic Simulation");
MainWin = new Fl_Double_Window(2, 12, ScreenWidth-6, ScreenHeight-24,
"Robotic Simulation");
MainWin->resizable(GL_MainWin);
SetGUI(MainWin); // Call to add the menu windows and a menu bar
If I don't add the windows to MainWin, I get the proper hierarchy and event
catching (maybe done by Windoze) but when I add them to MainWin, I go back to
the same problem.

When I leave the subwindows as top level windows, I only need to call show()
once for them to pop-up. Why do I need to do it twice when they are added to
MainWin???

Thanks! You've saved me many double-clicks to maximize my window
