I found it twice, once there and once for connected devices. In the Foxit pdf reader Search is under Tools. jsw Ok, but only one of those counted. Mike PS. I'm no long a skeptic. :-)

You still need a commutator to make DC. ;-) Tim -- Deep Friar: a very philosophical monk. Website: http://webpages.charter.net/dawill/tmoranwms
From: Josepi on 22 Jun 2010 22:49 ooops Electrostatic charges are DC! When they discharge the electron "inertia" usually makes them overshoot the equalibrium and then over shoot back giving an AC with high frequencies and lots of RFI. ready for the RFI coming?
