Perhaps this is bug 6517 (http://www.lyx.org/trac/ticket/6517), which I closed previously. There seem to be 2 factors contributing to the crash: 1. use of Qt4.6 (which I had tried for a while but switched back to Qt4.4 which seems to be working fine, and when I couldn't reproduce it with Qt4.4 I closed the bug report), and 2. multiple windows open upon quit, with the "Load open files from last session" preference option checked. Under these conditions, simply launching LyX and promptly quitting causes the crash. Can you reproduce this? BH
