Hi Jason (right name)
Just create a basic design using a preset ie 2 column fixed width.
When I try to change the text colour for headings all looks ok but the page it creates does not have those changes and when you open Sculptor up again they are back to default.
Thats all I did. Its easily got around by a manual edit so its not too annoying but would be good if it worked.
Im having to make a change save then go back in make another change just in case they do not save.
