How did you relate that to number of cores? Your code needs an awful lot of work. You've got source that does nothing, Swing GUIs started off the EDT, non-conventional variable names and indentation, and the issues Joerg mentioned. Check out the Java online tutorials at oracle.com and snoop around there for the Java coding conventions. If you make a request to the newsgroup, you have to actually state what the request is. Thank you for responding to our questions. -- Lew
