Hi Doug,

You are right with the silly humans:-): Adding a title and a desc is
indeed another (and simpler) solution. Indeed, adding both is even better.

However... Sorry to disappoint again with the Mozilla implementation,
but it seems that your hack does not work either:-( I attach the screen
dump of my Mozilla window. What does seem to work, however, is to set
the text to visibility="hidden", instead of playing with the opacity
value...

Thanks

Ivan
