Hi, I have a situation with a recursive Dr. Geo script where the image crash or get locked (Can't hold on the image). I tried with latest VM as detailed in the joined crash dump.
I did not get similar problem with other recursive script. So I may have very special interaction between the objects, but I did not find out. It may also be related to Morph because when instantiating first the canvas and its window (2nd line of the script), then the rest of the script, it does not crash. The crashing image itself can be found there in case of usefulness https://www.dropbox.com/s/rur8ayt8eon6mab/drgeo.image.zip?dl=0 When not crashing it outputs this cherry tree. Thanks Hilaire -- Dr. Geo http://drgeo.eu
