style reverts back to Cabo ..
I just downloaded the CSS Sculptor today and am having the same issue. I customize the colors out the wazoo and lose them all the second I click back into the CSS to make changes .. it goes back to Cabo (first on the list) with default colors and everything I did is gone.
Very annoying .. I really hope this is because I don't know what I'm doing with this thing .. at this point, I'm tempted to return it. :(
