Using 1.1.11 on Windows XP I started a transcoding, then doubleclicked a movie file in explorer. The transcoding was interrupted and the clicked file started plaing in that instance.
This is IMO wrong.
It should have been opened in another instance or at least it should ask "Interrupt the transcoding?".
I have the default settings, so "Allow only one instance" is off, the "One instance when started from file" is on.
