on this page of taming the Sax:
I don't see the various scale names in the grey boxes to the left of the staircase.
If I click on the grey boxes, the various steps of the staircase change to show the different scales but I don't know which scales they represent.
I am running Firefox 10.0 (updated today).
I have never looked at the pages before, so I don't know if it's a recent problem, related to the firefox update or if it has been like this before.
