Here is a modified cube.cxx example: http://www.fltk.org/strfiles/1707/cube_v2.cxx ... especially around line 192. The behaviour is the same in the official 1.1.8 line. It seems indeed not related to your utf-8 work. Ian, thanks for your comments. kind regards Kai-Uwe Behrmann -- developing for colour management www.behrmann.name + www.oyranos.org + www.cinepaint.org
