Make a list of implicit curves:
Curves=Sequence[-x³ + x + y² = i, i, -2, 2, 0.5]
The list of implicit curves disappears when Line tool is active
and the cursor is touching the curves in the Graphic View.
Almost every tool causes this problem.
Examples of tools without problems: Point tools, Reflect, Rotate, Dilate...
Is this a know bug?
I am using:
GeoGebra 4.2.60.0
Windows 7
Java: Version 7 Update 25.
See attached file.
The same problem
