JScrollPane makes a double content drawing.. how to avoid it ?

Hi, I'm developping a game tool in which I'm using a JScrollPane containing a JPanel for which I have redefined the paint(Graphics) method.

In order to have the fastest possible rendering, I have disabled the double buffering and defined my panel as opaque.

My panel is drawed twice when the scroll pane updates ( when resizing or repainting overlaped areas ).

How can I avoid my panel's paint method to be called twice ? Is it normal ? Is it a bug ? I'm using the J2SE 1.4.2_01.

Thank you..

Alexis.
