------- Additional Comments From felix@derklecks.de 2006-28-05 07:14 ------- after further playing with the program i found out, that without the Tahoma font copied to windows/fonts/ the glyphs are showing up correctly for a short moment.
Slowing down the program with strace the glyphs are displayed correctly for a quarter of a second or so. After that they change to the black squares that can be seen on the first screenshot.
