Sequence of LowerSum causes error when opening file
There's a problem opening files with LowerSum inside Sequence. Create an sequence
and save as ggb file. When opening the file Geogebra gives an error "Opening file failed". Despite the error message it appears to load ok, however the graphics 2 and 3d graphics views are broken, they appear as grey panes.
Example ggb file attached.
