Nope, but I can tell you that you are not alone! We have also frequently experienced these kind of problems with Lectora, both 2006 and 2007. I seems to be a bit more stable now, but occasionally crashes. The trick is to never repeat the previous action once it crashed. When it crashes when you publish a title, restart and save, make some changes and save again. Close it, reopen and then start to publish again. Btw, we use 2007 and its SP1 now, and it seems to work fine.
