Yuck...! If you have an electrical insulation problem, and your desk is metal, I'd _really_ urge you to replace your hardware completely, or have it properly insulated by a professional electrician. An electric shock could cause real pain() and panic(). ;-) But seriously, if that's the only reason for the panics, it's a pretty strong hint that you have an electrical problem: when ICs are underpowered, they tend to behave erratically. > -- Schlake -cpghost. --=20 Cordula's Web. http://www.cordula.ws/
