Input box is locked after choosing Symbolic
I have tried to open a new GGB-file, create first a function and then a input box, then create a relation with the function and then choose Symbolic under Algebra for the input box.
Afterwards I can’t seem to be able to enter the input box and write something in it. It seems locked.
I have experienced the same when first creating a number variable and in its properties choose Symbolic and then create a input box that is related with it. And it is the same if I then in the properties of the input box choose Symbolic.
I use the Linux version of GeoGebra 5 Classic from February 2020.
