Geoffroy,
The arrowheads still reading their actual color I find only happens with my polyline tool. I checked straitght lines, arcs, label tool and splines. These all show per my ghost stroy color selection correctly.
You can set the color of your ghost story by going to the story options window, CTRL/CMD 7, and clicking on the options button.
