I have not found any reports of this behavior. When you re-launch LabVIEW does it offer to investigate the error? If so submit the error log so that R&D can look into the crash. If youa re not asked to investigate the error, select "Help>>Investigate Internal Error..." and see if there are any error logs. If there are submit them, and you can alos search on the file and line number to see if there are any KnowledegeBases about them.
