I'm sure this has only started with the last couple of versions, and seems random.
Situation: I put a file on the timeline and then at some point, remove it. I then want to delete the file from Windows (or move it). If I go to Windows Explorer, when I try to delete it, it says the file is in use by Magix and can't be deleted. If I try to delete it from the Media Pool, same thing, it says the file is open.
This is annoying because I have to close MMS to be able to delete the file.
Occasionally, and I haven't figured out exactly the situation, I can delete files with no issues from either Explorer or the Media Pool after I have removed them from the timeline.
I'm curious whether others have come across this.
