Older construction now not working properly
I've made a construction last year which i tested several times and found it working as expected. 2 weeks ago I tested it again, to find that there is a partial malfunction. Nothing was changed in the construnction, so I think there is something changed in GeoGebra.
You can find the Construnction here. It works as follow: When you press the upper button, a new motive shows, which you have to reproduce by picking the correct colour (by clicking on the points n the left) and "paint" the cyrcles (by clicking on them). When you finish, you can press the other button to see if you manged it.
The check was successful till now. However, it seems to fail sometimes. I tried to reproduce the construction and found that the problem is in the upper button's code. When you press it, it is supposed to colour the first circles according to the rundomised motive. However it sometimes paints one or more circle with wrong colour (not the one in the motive) so the user sees a wrong motive, which, even if he reproduce correctly, fails the check (which is made comparing to the list "Μοτίβο").
Any help appreciated.
