Thank you for your hint - this works for all subwindows except for the main window "yast kontrollzentrum", those readings stay as small as they are. Still I do not understand why you mark this as "fixed", I cannot imagine that a normal unexperienced user will start editing configfiles by hand ... This would be fixed if there was a configuration dialog or a simple way like strg - + to increase font size. Take care Dieter Jurzitza
