To end or terminate an Ax session, you must follow these steps:

  1. Click any active Ax Window

  2. Simultaneously press Ctrl + Alt + End on the keyboard

  3. Click "Log Off" or "Sign out" option

This will force Ax to close, and when you open the program, you will have a new session.  *If you simply click the "X" button, your session will not end.   It will just re-open wherever it was at when you clicked the close button.
