psltscale changed in R2004?

I have drawings with multiple layouts, some with varying scaled viewports. Normally, to display all linetypes the same in each
viewport regardless of view scale factor, one would set psltscale to 1, and all would be sweet, but in R2004, it must be set to 0, and, set for each individual layout! The doco still says that the variable is stored in Drawing, but it appears not to be true.
Any clues?
