```Andreas,

As we are writing about bogus, you can explain me one aspect of the
profile I found hard to interpret. If you look at this profile snippet
(I hope it will print in a readable form):

The way the message calls are nested in the profile result, for me it
says: DrGSegmentCostume>>redraw is called in the context of
DrGAngle3PointsCostume(DrGMathItemCostume)>>update which is absolutely
not the case. So what is it?

Is this OpenQwaq system profiler located at the image level or VM level?

Thanks,
