FYI Both of these issues are known and the dev team is working on them. The lingering after shut down issue affects Windows and Mac and has proven to be quite elusive. Some task or combination of tasks sets up the shut down issue, the "IT" factor. We've yet to find the actual cause of that one. If any of you figure out the particular combination of tasks to trigger the shut down getting stuck please let me know. I've been hunting that "IT" for months.
