Within the context you describe, I can get it to work consistently, as long as I clear the command window of the posted "hello" before performing another "DO " ...

But "my" question is: is your "app" actually incorporating the "command window" ?

As far as I know, once you have an app running, you will never actually see a command window until the app exits ... and only if it exits to the "development environment"; not a typical scenario for a "distributed app".
