Same problem as Cologne
I am having the same problem. I am using DW CS4. I created a new style, made some changes to the layout, background, text, etc. I then saved out my new layout as a preset with its own unique name. When returning to the program to make some more changes I clicked on the "Preset Manager" icon for CSS Sculptor, located my design and clicked on "Edit". I then made some more changes to my design. When I was ready to quit I clicked "Finish". Then "Finish" again, then in the Preset manager "Done". None of my changes had been saved. There is no "Save as" checkbox when editing, only when creating the initial preset. It does no good to use the "New Sculptor" menu. Sure you can make changes, but it also creates duplicate files in the DW tree. Can you help?
