Crash reports from apport are only sent to Launchpad, where you would have a browser window opened to add more details, if you are running the development release of Ubuntu (currently Artful Aardvark). Otherwise, crash reports are silently sent to errors.ubuntu.com. If I recall correctly, the design decision was to make apport as unintrusive as possible hence there is not a second dialog displayed saying "Yes, it was sent". That being said perhaps the dialog about sending the crash could be modified to notify you that no further action is required.
