Didn't work! I copied the whole folder over and DW just renamed it and created an new configuration default folder!
In the old original configuration folder, there are all of my xml files -- one for each setting. Can I import these into each relevant extension? Will this work? It'll take time to do, but at least my settings are thereof it's possible. I'm not sure if the xml file is enough by itself though, so I don't want to go ahead and do it just in case I destroy DW in the process!
Thanks so far Ray.
