Sometimes Audiqueen throws an error message “Unhandled exception has occurred in a component in your application.”  This is a window-related memory error.

You may try to solve it by lowering the value of the parameter StandbyTimeInMinutesBeforeAutoShutdown

For this, open the Audiqueen Administrator (under the top left Audiqueen Icon; you need Administrator Rights!); then click on Audiqueen Settings Configuration and find the parameter under the Advanced group.  Its default value is 480.  You may try to reduce it to 240.
