Jose and Jurgen, I propose that we apply the attached patch to partially solve this problem. It allows lyx to start even when textclasslist is empty. If lyx is started like this, only reconfigure (and quit) is allowed. This gives users a second chance to configure lyx if initial configuration fails. This does not change command line usages when configure.py fails with a newly installed lyx. For example, 'lyx --export pdf blah.lyx' previously fails to run at all, and will now fails to export. I plan to add something like --defer_configure so that configure can be automatically executed *after* lyx/GUI starts under windows. This should wait until the output of configure.py is displayed in a dialog. (Abdel, any interest to do this?) OK to apply? Cheers, Bo
