Problem with setXORMode

QUESTION
1. I am trying to do setXORMode to a string, and it does not work. The code very briefly is:


I draw a string on (10,10)
g.setColor(Color.black);
g.drawString("aaa", 10,10);


Then
g.setXORMode(getBackground());
and
g.drawString("aaa", 10,10);

ANSWER
Some platforms implement text drawing very differently from graphics drawing, and I think the the MS implementation is one of those that doesn't support the XOR mode on text.
