I don't use display states. So I usually uncheck the "link display states to configurations" box, and delete all of them except "Display State-1". This cleans up my config tree a bit, because I don't have a bunch of long winded display state names showing up next to my config names.

With SW09, it has started to create a "_PhotoWorks Display State" automatically after I've cleaned them up. It shows up when I double click on a config.

I don't have the Photoworks add in turned on.

Why are they there, and how do I stop them from being created?
