Users, A problem has recently sprung up on my PC where there was not one before. stereo_image_proc does not display any subscriptions, nor does the any node that subscribes to it show it as a subscription (using rosnode info and rxgraph). However, the node does get images from a Bumblebee2 camera and display the disparity map. These might be clues to the main problem: the disparity image only updates at 1Hz (exactly). I highly doubt this has anything to do with the speed of my PC-- I could formerly display disparity images at 25-30Hz. Thanks, Sean
