Disabling automatic excerpts

Hi

I’m using Bueno for my site, and before the big update I was able to decide where the excerpt on the main page would end by clicking the ‘more’ button. But with the new version, Bueno automatically cuts off posts and ignores this function. I’ve tried switching things around in the theme settings, and the solution to change something in the code doesn’t work for me, since I can’t find that specific line of code. So does anyone know I can change it so that the homepage shows full posts, unless I used the ‘more’ button, and in that case, cuts it off where I chose it to?
