design rules / flatten layout

Thanks for this tool.
I try version 8.03 of the Electric VLSI Design System (Linux x86).

How about the bug "Technology editor cannot edit design rules."
What can I do to add a new technology with design rules?
The items can be changed but not be saved after closing window.

It would be nice not only to use the output-files of assura or 
calibre but also read the input (technology) files?


What do I have to do to flatten the layout, is it possible?
