Hi Bjorn,
I just looked in my "Styles" folder and I do see the file "_JWLTZAS.sty" here on my system.
Also, it does show in the StylePicker here as being from RT set 217, so you are definitely correct about the set number.

So you're saying that you don't see that file at all in your "Styles" folder, or are you just seeing it listed as N/A in the StylePicker ?

Just curious, did you use a tool such as "Pacifist" of "Suspicious Package" to determine that the file is not in the 214-220 install pkg, or did you just run the installer to make that determination ?

I will have a look through my RT installer files when I get a minute to see if I can find that file in one of the packages.
I will let you know what I find.
