Version: (using KDE 4.1.2) OS: Linux Installed from: Ubuntu Packages I've upgraded from KDE3 and found that KDE4 still interprets the "mac style" menu option from ~/.kde/share/config/. It doesn't work properly and just hides menu bar from every KDE4 application. I guess the option should be ignored unless it's fully implemented. (The current workaround is to edit RC files in ~/.kde/share/config/ manually or just kill them before installing KDE4.)
Moved to "plasma" I hope to have selected the right component :-)
