We use the Application Event Log to report errors or unexpected conditions. This means they will never get lost but you do need to check the log from time to time.
In particular we use an advanced technique called Structured Exception Handling. This means that absolutely any error inside ImageGlue will get reported in the Event Log no matter what caused it. Even errors that would normally crash an application or service are caught. ImageGlue will analyze the error, report it to the log and, if appropriate, automatically recover.
