Robotino View Marker Detection

[kerplunk]

Has anybody else had any trouble using marker detection or marker position function blocks in Robotino View? Every time I use marker detection and connect its output to anything else, Robotino View crashes. Whenever I use the marker position function block, I can not get the Robotino to recognize a marker that I printed out on paper. If anyone has successfully used these function blocks I would appreciate any advice on how to get it working.
Alternatively, does anyone know how to read a QR code or some other code using the Robotino and a webcam?
Thanks!

Did you try the latest Robotino View version? (3.1.2) There was a bug with converting floatvectors to single values which is corrected in this version.
