Today i change my document settings to twoside but nothing happened. I searched in the list archive and somebody had the same problem before, but there was no answer to his mail. Is there a bug-list on th Lyx side ? I don't find it there. I think this is a bug in 1.1.6fix3. Before (fix1) it works. I exported latex and in the tex file there was no option twoside. So i inserted twoside now in layout->document->options. This works now but an other problem appears: I have to put the TOC depth to 5 if i want all subsubsection in it (if i use oneside 4 is O.K.).
