Hi I'm running pd-gem on win7 32 bit, I was doing some webcam tracking and everything was fine but then I just left the pc with pd open for a few minutes and now the camera turns on but I do not receive any "life sign" into pd. no values in pix_blob outlets and the gem window is all white. any idea?
thank you

ok I just needed to restart my pc. until now I did not get the same issue again. Don't know what was it.
