Question:
Win32 AWT and other implementations have a "Close" box on the window title bar, and many apps rely on this as a way for the user to quit the application when all else fails. Is there an equivalent method which will work on ER5 devices?

Answer:
It is true that there is no "Close" box on the AWT window frame in ER5. Java developers targetting ER5 devices need to take this into account, and should provide a menu bar with an Exit or Quit menu item. It is an ER5 convention that a ctrl-e hotkey also be provided to exit an application, but this is not a requirement.
If you are trying to run an application which does not take any of this into account, you should be able to quit it by going to the system's "Open Files / Programs" dialog, selecting the Java application, and quitting it there.

This does rely on the Java app handling the WINDOW_CLOSING message, but this is a reasonable expectation. If all else fails, it should still in emergencies be possible to kill the app by using ctrl-shift-e in the the system's "Open Files / Programs" dialog - the closest EPOC equivalent to hitting Ctrl-C from the command line in Win32.
