It's in the final line...
SuSe is very much like Windows.
Thing is, if you change a configuration-file in SuSe you have to run suseconfig (not sure about the spelling).
If you don't, SuSe will simply overwrite your settings with what it thinks is better...
And suseconfig does take some time, depending of course on your computer... Everytime it runs I believe it goes through every
configuration file in you system!
So make your changes and then (in a console, I believe) run "suseconfig".
And if you don't like Microsoft - why run SuSe???
