I am working with files created using 2005, 2006, 2007 and 2008 versions of Lectora. Mine rarely crashes and I am using videos, animations, audios, etc. and lots of text boxes; but have had no real issues with it crashing. Knock on wood; I hope that continues and I didn't just doom myself. I am working with files created using 2005, 2006, 2007 and 2008 versions of Lectora.
