Is this a Bug in Geogebra?
lets try this:
Create a circle:
Now a function:
Now lets seek for intersections:
You correctly get the two points of intersection A and B.
Now lets save it as bug.ggb
Close Geogebra and open the file you just have saved.
You can see that the points A and B are now undefined.

Does it happen only to me?
