The sensor operator color() touching () does not work reliably in the Offline Editor(Win 7) The two versions of the line following scratch programs I have posted do not run under the offline version. If would appear that the sensor in the offline version requires movement of the sprike to cause the states to update. Mere rotation does not work. Even when there is motion, once the second color sensor combinations is activated none of the sensors work reliably and the line following ceases.,

This feature works well in Scratch 1.4 but not in the latest Scratch 2.9
