Error that occurs only when embedded
When you click an the top left checkbox in the embeded app it pops a message on script error for the "StartAnimation" line. This is a recent error (occured in the last 1-2 weeks).
If you reset the app and then pres the check box - there is no error.
On the geoegbra.org site there is no error.
Same error occurs in other programmed elements in lines with "StartAnimation" or "Zoom".
