Hi all, when I run image_view, the following happens: * It displays the image topic nicely in a small window (approx. 320x240) * When I move the window, try to close it or make it lose focus, it immediately stops updating its content or responding in any way, not even to ctrl-c on the command line. I've tried it in cturtle and unstable, same thing. I run Ubuntu 10.10 32bit. I've enclosed two gdb sessions where the above happened. Session 1 is after starting image_view with no images to display and clicking the close button, where the icvWindowThreadLoop hangsin thread 6; session 2 shows that after an image has arrived, cvShowImage hangs as well in thread 1. Help! David --- gdb session 1 --------------------------------------- Reading symbols from /opt/ros/unstable/stacks/image_pipeline/image_view/bin/image_view...done.
