Was having trouble with the Magic window rendering anything, and Preview was listed as being "stopped" and couldn't be restarted.
Searching the forums I found a note to delete the configuration file in my user folder's AppData\Magic account (Windows 10) and that's brought the preview back to life, however even without a Project open after clearing the configuration file and it resetting the UI, when closing Magic it hangs and does not close, requiring being force-closed as a hung task.

Apologies if this is in the forum already but searching for "crash close" or "hang close" resulted in nothing, however I appreciate keeping duplicate posts to a minimum.
Thanks in advance for any ideas.
