VLC stopped launching
I have been looking at a couple mp4 videos transferred from my son's phone.
I successfully opened 3 of them with vlc, closed vlc and renamed them.
Then for the fourth, vlc stopped launching.
Well I guess it is really not launching, as I see the vlc icon on the
panel. It is not responding. It won't close. It won't let me open a
file. It won't quit.
How can I find its process number to try and kill it or any better way
to get its attention?
thanks
