Abstract: An application is associated with a main thread that is running on an operating system. A secondary thread monitors the main thread to determine whether the application is in a hang state. A ghost window that matches the hung application window is displayed on a user interface and the hung application is hidden from view. An application crash is attempted on the main thread when the user closes the ghost window. If the crash is successful, any unsaved data associated with the hung application is recovered. Error information associated with the cause of the application hang may also be collected.

Abstract: Queued mode event reporting is provided. When an event occurs within a computer, an event report is generated describing the event. If the event report cannot be immediately transmitted, it is stored in a queue for future transmission. The queue for storing the report is chosen based on whether a user should have access to the report and on whether a notification should be provided to the user when the event occurs or prior to sending the event report or at both times. A queue trigger program is also configured to execute when the computer goes online and when a user logs into the computer. The queue trigger program causes the queued reports to be sent, if possible, and causes the appropriate notifications to be shown.
