I was using OpenCV3.2.0 with contrib as using ArUCo markers and using Python and i needed to re-install my OS. No problem with that - OS re-installed went fine (RPi flavour of Debian Jessie) and re-compilied opencv3.2.0 but now instead of getting 6 video windows on my screen when I run my program (one for each imgshow) - I'm only getting one which is anchored to top left and has icons on it inc left/right/up/down arrows
What have I done differently this time (and how can I get back to my old 6 separate windows)
regards
Simon
