The second puzzling result, which is still in evidence, resulted from editing simple_continuous_canvas.js so that an agent is shown as an unfilled circle of radius 10 rather than a filled circle of radius 2. Despite reverting to the original file, the visualization still shows the unfilled circles of radius 10. Again, I am led to conclude that the changes have been stored somewhere I can’t find them.
Can anyone suggest what is going on? Further details on request.
