Control menu that appears in JInternalFrame is much different than what we get in
native frame which lies insdie a MDI application.
Look at attached image: JIF_MenuCmp.PNG
Following are the clear visible difference between them
1) Native is showing mnemonics for Close.
2) Native is using icons for some of the MenuItems
3) Native have one extra button "Next" which on click takes to the next icon if there is one.

Native applications used
- Created a MDI Application using MFC VC++6(Created and build on Win XP only)
- Editplus (www.editplus.com) - It is a simple editor with MDI support
