[Vm-dev] Fwd: Linux desktop manager Close Window is dangerous.

[John M McIntosh]

Ok, well the other option is this more of a application event, where  
this close window event really means quit the application.

On the macintosh we get a quit application event which we ignore, or  
optionally for the Scratch people we have a VM setting were the VM  
actually terminates. This is used to terminate the Scratch VM without  
intervention if the macintosh user logs off or shutdowns the machine.

We could of course flow the event 6 when we receive the "quit  
application" event from the operating system.
