        tx.text = X11.app Customization Assistant.[return][return]This interface assists the  user  in changing settings that govern the behavior of X11.  The individual user can specify whether focus follows mouse behavior (emulating canonical X11 unix systems) should be set, whether the user should be  warned on  logout  if  X11 is running, whether X11 should be run as a dockless and menuless application in the background, as so forth.  An option to restore all default behaviors is included.[return]

        tx5.type=text
        tx5.width = 1050
        tx5.text = X11.app can be launched silently and without any trace in the dock or menu bar. (If you do this you will lose the ability to use the X11 menu and will have to launch X11 apps from the command line only.) PLEASE SAVE any work in running X11 applications prior to answering yes, as we need to kill the X-server before starting. No need to do this if you anser Leave It Alone.

        rb5.option = Yes, make X11 Dockless.
        rb5.option = No, restore X11 to the Dock.
        rb5.option = Leave everything the way it is now.

#       tx6.width = 1050
#       tx6.text = Set DISPLAY variable to allow X-windows programs to run from Terminal.app and iTerm.app. Fast User Switching creates the problem of multiple simultaneous instances of X11.app running and how to find the appropriate DISPLAY value to assign to each. Choosing "Yes" solves this problem.
