Hai there, great theme - really much thanks to everyone for this work!
My issue is that I am using WP 3.1.1 and Atahualpa 3.7.3 and I did also deactivate my plugins and still problems, when I drag my widgets to the right - under Appearance -> Widgets and leave that page, nothing happens on my site and all the widgets just move back to the left under the inactive widgets area.
This is a fresh install on a fresh domain.
Any suggestions?
