Understanding widgets

[natman]

Hi i have hardy RC kubutnu KDE4 installed and am liking it except one thing, when i save anything from Firefox it goes to the desktop, but when i go right click the on the desktop all i get is some widget menu, the only way i can access the file is via dolphin ( file manager or terminal ) also drag and drop wont work with the pseudo widgets things on the desktop - is there any way to make files behave as normal files in KDE4 desktop?
Also anyone know when Dashboard widgets will become available in KDE ?
