Normally the JVM terminates when the last GUI object is destroyed but this thread stays active (if it's not a daemon). I was wondering if there's a way to let it know it can interrupt it's own thread rather than having to remember to call a close method to interrupt it's thread from the windowClosing method. > If I want to shutdown a thread before the GUI terminates I usually create a stop method that terminates all the threads that need to be stopped before the GUI. If they are threads that can just be killed, I make them daemon threads and ignore them. -- Knute Johnson
