You wave the magic want vigorously through the component in question, and the fault generally stopped being intermittent. > I have often thought of applying this technique to the various bosses I > have had in my life to see if I can get them to make sense. > Unfortunately I discovered there was usually no module to extract. Not a problem for the magic want test - but it's still not recommended. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
