I am lucky with that, and I appreciate the frustrations of a fauly width setting. It should work, Period!!

Is the not working width stuck at wide or Narrow or in between?

I have never thought to set it as anything other as wide in my ageing system, but I understand there are plenty of reasons why sombody may want to control it for their personal set ups.
