You need to use the "transparent" styles for the themes on top,
and the odd thing is that you need a separate master layer
between each (which you must make invisible to see through it)
I did make it work with the States table. Basically open the
table in a mapper, and create your first theme. Then add a second
copy of the layer to the map, and them that. Be sure to choose
only one of the "transparent" pattern themes, and make sure each
theme is above a separate copy of the map layers (use Layer
Control to see). Finally, turn off the visibility on all master
layers between the themes (answering "No" to question it asks
you. This will work, but what won't work is trying to add a
second theme to a layer that already has one; even if you choose
a transparent pattern. Each theme must be based on a separate
layer, but you can use multiple copies of that layer.
