Mi app is opened by the browser to handle a Mime-type. When It makes some process I want to close it but not the browser.
I've tried Exit() and User::Exit(0). In the first scenario the app closes, but the browser gives me a CONE 30 error.
The second case closes both the app and the browser.
I usually call Save() before the Exit() line,a nd then in your AppUI's destructor you need to call the Notify fucntion call for the doorobserver, so the main app knows that the embedded app has closed.
