I tried modifying the 1-General Settings_.py file from 1.0.12 (which contained workspaces with different bar configurations) to make it work with 1.0.18.
This is the result: http://pastebin.com/3TW5xgGd
However when running the program, windows from the first workspace appear in all other workspaces. Also if you click those windows from the different workspaces, the program crashes.
I might not be aware of how some of the changes since that version (specifically the multi monitor changes described in 1.0.17) changed the way the configuration files work.
I'm using win7/64 with a single monitor.
