Had to re-install Mandriva 3 times today - I put it all down to KDE4. First, my widgets were going all over the place. I couldn't restore the task bar to defaults (no time to fiddle with a fresh installation), I decided to do it again. Second time, RPMDrake (Install/Remove) applications locked. My wireless connection stopped connecting for no apparent reason. After failing to reconnect my wireless router or install applicaitons - I decided to go back again to the drawing board. Everything works ...
