AME does not 'release' file locks

version 20 (and all previous) - Windows

Is this just me, or does everyone have this problem and it should be a wishlist item?

Once a file is done processing with AME, I cannot delete the source files until I close AME.  As I am working I have to continually close and restart AME so I can move or delete files that I am done processing.  Once AME is finished processing each item it should release the OpLocks.  Or at the minimum, do that if I remove it from or clear the queue.
