Yes, thanks - I'll change the kdejava/README to use KScribble as a demo 
app/confidence test. It goes well with having QtScribble as the equivalent 
example for Qt.

Send me any fixes/additions, and I'll put them in the cvs.

KIconLoader.UserIcon() is one of the new static methods added to 
KIconLoader.java:

/**  Load a user icon.
*/
	public static native QPixmap UserIcon( String name, KInstanceInterface 
instance);

So it should work ok now.
