We are using Thymio robot and Aseba environment for educating. But we have a problem in opening your playgrounds and our playgrounds that we made.
The problem is in some computers that we run Aseba playgrounds on them, Aseba playground doesn't show the lines or more specific it doesn't show the playground's PNG pictures.
Png pictures
Summary:
In a few computers when we run aseba playgrounds, it doesn't open playground's Png picture.
