Pharo crushes

hello everyone  I am working on project and we are using Roassal for visualization, the problem is that every time i execute my code Pharo crashes ( using the latest image 6.0 on Windows 10 64 bits machine), knowing that the same code runs fine on my collaborators Mac OS machines. Is there any solution that you could offer in such case ?  Moussa Saker LISCO Laboratory Badji Mokhtar-Annaba University, P.O. Box 12, Annaba 23000, Algeria
