How does Crash Recovery work?
“Many crashes in DAW software are caused by plug-ins causing ‘exceptions’. That’s a kind word. Normally when this happens Windows will display an error and the application is terminated, typically resulting in data loss. SONAR 6 now attempts to detect such exceptions before the application is terminated and allows you to save your work. A dialog is displayed which allows you to save a copy of your currently edited project before SONAR shuts down. In most cases you can save a valid project when such a crash occurs. This can save you many hours of lost work in the case of a ill timed crash.” (SOURCE: Noel Borthwick, Cakewalk (http://forum.cakewalk.com/tm.asp?m=864813#)).
