hi Dominic,

Thanks, but this solution doesn't work. When the application is started on the bridge, using a command similar to:

my_app = obj_new('my_application')

this command executes normally and the bridge status is set to 2 (command completed). However, if you kill the bridge now, you would kill the whole application. What you need to do is wait until the application is closed by the user (it is a GUI application), and only then can you destroy the bridge.

The question is, how do you check if the application is closed? Any call to Execute or Execute, /NOWAIT will get stuck if the application is busy, even though the bridge status indicates 0 or 2.

thoughts?
