Inside a glass case I have one insulator that will not stay put. It's a light aqua No.3 Cable. It creeps out of line a bit then I pull out the case from the wall and put it back. After a few times I decided to let it go, monitoring it of course, to see where it wanted to end up. It turned left as it crept forward and has made contact with a smooth base Hemingray No. 3. It's been that way for a while so I guess the movement has been halted. Guess I'll move it back and tack it down with something sticky. The question is does anyone else have a problem child like this that creeps or crawls to vibrations while others around it stay still?
