(ie, maybe it's a design problem). >Any war stories on returning defective merchandise to 3COM? Sounds like a defective card. Perhaps flexing the cable also flexes the PC board inside the card causing it to short against the case. Or pehaps they didn't trim the leads on the connector flush enough so that they short when the cable is flexed. I have one of the new connectors with the ears and have not experienced a single bit of flakiness - I snag the cable with my foot all the time...---------- Jim Lee Diamond Quest Consulting leejim@peak.org 30563 Ridge St http://www.peak.org/~leejim Lebanon, OR 97355
