3.6.6 is not working for me, in that the SAVE BUTTON, for all pages, is missing. I followed a suggestion of trying Ie instead of Firefox, but no luck.
I initially installed suffusion from inside wordpress. This was not good.
Alternatively, I tried to download and unzip suffusion (from WP); however, the 3.6.6 would not unzip ( using 7-zip ).
I them uploaded the older version 3.6.3, after I unzipped it; and this works. The SAVE BUTTONS are back.
Nice theme or framework. Extremely complicated, and some of the terminology ( eg "visual effects" ) is somewhat puzzling at first. But I have to give extreme accolades to the developer of this highly rated theme.
