Start Task and Event Loops

Question

I have a Window with an Event Loop that looks like this:
Event Loop
when StartButton.click do
SO.EventLoop;
when StopButton.click do
post SO.Z;
End Event;
I have ServiceObject (SO) that has an EventLoop that looks like this:
Event Loop
when X do
start task Y();
when Z do
exit;
End Event;
The Event Loop on my SO is not catching Z until Y finishes processing.
Does anyone know why? Is there another way do this so I can catch Z
before Y finishes?

Could it be that the StopButton.Click() event is not being trapped? That is, the window's event loop is waiting for the SO to complete, as it is a synchronous task. Therefore, use:
when StartButton.Click() do
start task SO.EventLoop();
Anyway, I would think that a better way to do it would be to have the SO's EventLoop running initially. That is, start it (as a separate task) elsewhere (perhaps when the window is opened). Then, when you get the StartButton.Click() event, do:
when StartButton.Click() do
post SO.X; -- This will cause task Y to begin
Hope this helps...
