Hi, I have a crash with data loss with the latest 1.4.x SVN. Open http://www.csse.uwa.edu.au/~john/lyx/modal_MF2.lyx in lyx. Do an "accept all". LyX will lock up, it will not write an ".emergency" file, unless you go to the console and press Cntl-C. Even then, LyX will not exit.
Also, accepting changes in the file http://www.csse.uwa.edu.au/~john/lyx/modal_MF.cannot.accept3.lyx will cause a crash. (Less serious since at least it writes an emergency file). -- John C. McCabe-Dansted PhD Student University of Western Australia
