KDE notification windows

In default configuration, the info windows informing (for example) about the completion of copying the file, are displayed in the top left area of the screen. They require to be close manually than because otherwise you can not even click on the icons that are under such info window.
I want to change that. in such a way that displayed the info dialog window will act as a pop-up window, from the the bottom task-bar.
So it was in Mandriva.
How can I change the KDE configuration to do this to be possible ?
