Different behaviour of the desktop geogebra app and the geogebra web interface
Not a Problem
Hello to everybody,
I'm building an activity designed to study the electric field and the electric potential field.
One target is to show tha electric lines are perpendicular to the isolines of the electric potential field. In order to do that, I overloap two svg files (created using gnuplot and inkscape) which have different sizes.
Exploiting the geogebra feature, I fix three corners of each figure using the same three points.f
This works fine in the geogebra desktop app while the same behaviour is not obtained when I share the activity on the web interface.
I attach a file which shows the screenshoots relative to the problem described.
I hope that somebody can help me.
Best regards.

Please post the link to your activity
Thank you for your reply.
I''m sorry for the inconvenience.
This is the link of the activity: https://www.geogebra.org/m/sdu7ccec
It looks fine to me - what's the problem exactly?
I have found the problem, but it is not related to the geogebra app.
The strange behaviour is visible only if you open the activity with firefox, if you use chrome the activity works fine.
Thank you very much for your help.
