Prevent maximized windows being dragged and resized (kde4)

The Mrs is not so accurate with the mouse and playing kpatience etc… she seems to click the top or bottom edge of the maximized window ( as if to drag a card ) but ends up dragging the window, which moves and re-sizes

I tried it in Gnome and my maximized windows don’t drag.

So is there a solution for kde. I guess it’s a feature. I had a stab around in systemsettings, but couldn’t put my finder on it.
