Bill,
I think you can shut this down... Sounds like to me that you are using your Console Window for work... The console window's purpose is to capture error messages so they don't appear on your monitor or another terminal... I have my users run the iconified console on their desktops and (depending on what OS you are using) use a terminal (xterm, dtterm) for work. The error messages should not appear on this type of terminal unless there is no console running.
