Geogebra classic applet not showing drawing
I am a teacher teaching technology, I downloaded GeoGebra classic applet for making drawings. The applet works well. I used the same applet on Moodle assignments but now my problem when I open the GeoGebra as teacher to mark it doesn't show the drawing to mark. Any suggestion that can help? I have attached a picture to illustrate my problem, when I click Geogebra icon nothing comes out.
