Works great on my tiny iBook to control my massive PC desktops.
just downloaded chicken to new iMac running 10.9.1 and connected to linux Red Hat Release 6.4 running x11vnc 0.9.13 and got nothing but rectangle errors. Downloaded the OLD Chicken of the VNC and it works out of the box....but this could be old drivers on the linux side??
Works most of the time stable and robust, but after a time a "Connection Terminated - Unknown message type 12" Error occours and then *no* connection to the host -which worked flawlessly before- is possible.
