Version: 4.1.4 and up (using KDE 4.2.0) Compiler: gcc-4.3.3 CFLAGS="-O2 -march=pentium4 -mmmx -msse -msse2 -fomit-frame-pointer -pipe -w" OS: Linux Installed from: Gentoo Packages Since upgrade to kde4.1.4 (and 4.2), whenever konqueror or dolphin are opened (either via commandline or krunner, or opening a folder from the Folder View plasmoid) they now start in fullscreen mode. I can find no setting in either program to prevent this behaviour. In 4.1.4, switching to normal (windowed) mode in konqueror and quitting meant that it would be windowed when re-opened (though it would return to opening in fullscreen after a reboot). I didn't check whether this was the case with dolphin. With 4.2.0, both filemanagers open fullscreen again after being switched to windowed mode and restarted. However, issuing "kfmclient openURL <some local path>" on the commandline opens konqueror (which is set as my system default filemanager) in windowed mode. This is under Gentoo x86 unstable; the issue has also been reported in Ubuntu Launchpad here: https://bugs.launchpad.net/gentoo/+source/kdelibs/+bug/324232/
Note that the Ubuntu bug was reported as happenin in Gnome. From KDE on 4.1.4 I cannot reproduce this on Kubuntu.
Sorry, this is a red herring. I didn't realise it was a window-manager issue (which in my case is compiz + emerald, not kwin). I've followed the advice in the launchpad bug and resolved the issue. Konq still appeared with the menubar disabled, but I've changed that setting and it's survived a restart of the program, so I'm guessing it'll survive a reboot too.
