Handle multiple errors without using multiple modal dialog popups

[gentleben8282]

When there are multiple concurrent errors, there should not be multiple modal dialog popups; there should be an alternative mechanism, such as an error log, on the default screen. Also, when multiple errors occur concurrently, the user should be able to continue to maintain full control of their keyboard and mouse. Finally, the cadence of errors should be taken into consideration; for example, how should 10 errors occurring within five seconds be handled?
