[Pharo-dev] [bloc] how to get a debugger

[stepharo]

Hi

I got a red square of death and I can inspect the blMorph but I cannot 
get a debugger to understand the drawing problem?

rawOnAthensCanvas: aCanvas

    super drawOnAthensCanvas: aCanvas.
    aCanvas
        drawShape: (BlShape new
                            strokePaint:
                                (BlStrokePaint new
                                        paint: (BlColorPaint new color: 
(Color blue));
                            width: 15);
                path: BlCirclePath new).

and when I select

(BlShape new
                            strokePaint:
                                (BlStrokePaint new
                                        paint: (BlColorPaint new color: 
(Color blue));
                            width: 15);
                path: BlCirclePath new).

I can inspect it.
