Due to user requests, (and a really good post by Rosie here: 156920.aspx), we'll be adding the options to "Work Offline" and "Use blank layout" when starting Logos 4 with the Cmd key held down in the next release.
What does this mean for you? If you encounter a scenerio where the app is crashing using your last saved layout, you can simply restart with the Cmd key held down and select "Use blank layout". Logos 4 will reopen with no tabs open and you can then keep working. You won't have to delete layouts.db and recreate your layouts if you get stuck!
