I registered the __geturl() event handler but it never gets called.

How can I determine if the events are being sent to MyApp ??
I tried:
  $ export AEDebugSends=1; export AEDebugReceives=1
  $ open myapp:xyz


Obviously some event is causing MyApp to open when I type "open
myapp:xyz", but does that actually mean MyApp will receive the event or
just some internal framework that causes the application to be launched ??

Thanks, Brendan.
