Login issues after new Mageia 3 KDE installation

Hello,
I attempted to install Mageia 3 KDE over the existing partitions of a computer running Mandriva 2011.
However I am experiencing problems logging into KDE.
If I boot into Mageia 3 I am never presented with the login panel where you can select the user.
Instead I am taken straight to a KDE desktop. This desktop has no desktop icons and no task manager bar at the bottom.
It does have the desktop widget in the top right corner. If I use the desktop widget and invoke leave then I am taken to the login panel where you can select the user. Here I see my user but I cannot enter a password. I cannot get the cursor to show up in the password field.
If I boot into Mageia 3 Safe Mode then I can invoke KDE 4 from the command line. And I am taken directly to a full desktop with desktop icons, the task manager bar at the bottom and he desktop widget. From here if I invoke the MCC and go into Manage User then I can see my user and nothing stands out as strange. I assume I am root when in Safe Mode since I am not prompted for the root password when entering the MCC.
All advice would be greatly appreciated.
