Minimize Java applications on S40v6 S40v5

1st open any java game/app in WinRAR (or another if you like) & enter the "meta-inf folder" and open the notebook file MANIFEST.MF

2nd paste at the end of the line,
Nokia-MIDlet-no-exit: true

3rd save, copy the game/app to the phone and launch it,

4th then briefly press the red handset and the phone no longer asks for the closure, but it minimizes, and to return to it again we need to fire up the folder.

The only drawback is that the phone at about 2 min questions and "show [name of the game / application]?".
