I've fixed the problem with this in my FMain.class ...
*Static Public Sub _init()*
* If Not Exist("/tmp/dish_opened") Then Wait 2
File.Save("/tmp/dish_opened", "true") EndifEnd*
that gives a couple of seconds and then the
org.freedesktop.login1.Manager.PowerOff() function works
if app is closed and relaunched it finds the file in /tmp/ and does not
wait and dbus is still okay.
Seems any call to Dbus like DBus.System.Applications.Exist() in _init()
initialises dbus too early, it finds the login1 DBus.System.Applications
but the Interfaces do not work.
So the fix above is all i can think of.
