I'm trying to use [pix_opencv_facetracker] on a windows machine and there's something strange happening. I'm opening the help patch and the camera is projected properly, but the face detection stuff (the outline of the face and the frames/sec) are being projected upside down. I can use this help patch with my OS X machine fine, but with this Windows 7 machine, I get this strange behaviour. I've installed Pd-extended-0.43.4 and pix_opencv from here https://github.com/avilleret/pix_opencv
