What do you mean a window gets eaten? Are you referring to focus? Enlightenment allows you to change focus anyway you want including, just moving the mouse over the window. But then again, you would have to actually pay attention to what you are doing, which strobe obviously does no like to do.
KDE and GNOME are Desktop Environments. Enlightenment, WindowMaker, BlackBox, Sawmill, etc are all window managers. You can run pretty much all Gnome/KDE applications from within Enlightenment. Enlightenment allows you to customize EVERY part of the interface, whereas KDE (using KWM) is not very customizable. The latest version of Enlightenment available is 0.16.5, they are working on 0.17 which is pretty much a complete rewrite that will take the place of the Desktop Environments. I cannot wait to see how it turns out.
