Suse 9.0 + KDE 3.2.3: First and second hierarchy of the KDE menu are seperated

HI! I have updated Suse 9.0 to KDE 3.2.3 with yast. Now the first and second hierarchy of the KDE menu are visibly seperated and there are no arrows in the first hierarchy items where there exist sub items. From the second hierarchy on, it's OK. This is a little hard to explain, so please look at this screenshot: http://www.boerkel.de/kdemenu.jpg Since this looks OK on the sample screenshots at kde.org, there must be something wrong with my system. Anyone any idea? Thanks! Thomas
