Simply you are adding an useless Lock() that prevents the Blit() from happening (Bliting/Drawing to a surface while it's locked is not allowed). -- Claudio Ciccani [EMAIL PROTECTED] [EMAIL PROTECTED] http://directfb.org _______________________________________________ directfb-users mailing list directfb-users@directfb.org http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-users
