No, my problem was with detuning the B string (although several keys are tight and may become a problem, too). The counterclockwise turning of the key to lower the pitch of the B string, will also unscrew the key when the tuner sticks. If this had been at a gig, I'd have been stuck with a sharp B string and no way to tune it down to correct pitch. Every time I tightened the key back on, the B went a little higher. And I couldn't get it on tight enough to detune the string cause the post would turn. So, I held the shaft that the key screws onto with pliers, so it wouldn't turn, and tightened the key on. Basically, someone didn't anticipate this happening when they designed these tuners. And, it's probably an easy fix like lubricating them. I just wish I hadn't scarred my tuner up

I'll give Sheldon a call. And thanks to you and Sheldon for the help.
