FULL PRODUCT VERSION :
java version "1.6.0_06"
Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
Java HotSpot(TM) Client VM (build 10.0-b22, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
When a JFileChooser is instantiated from my (signed) applet and create a new folder via the "new folder" button, it's impossible to change its name from the default "New folder". When I run the same code as an application, everything works fine.

Under Linux the applet works as expected.
It still worked under Windows with JRE 1.6.0_03 and stopped working with JRE 1.6.0_04.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and run my testing code below.

When I put it in a jar, sign it and run it from a html page in Internet Explorer or Firefox under Windows, I can't rename newly created folders. When run as an application via the main method, everything works fine.
When run under Linux, everything works fine no matter if I run it as an applet or as an application.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Newly created folder should be renamed
ACTUAL -
default value "New Folder" can't be overwritten, pressing "enter" or "escape" has no effect

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import javax.swing.*;

public class Test extends JApplet
{
public void start()
{
JFileChooser c = new JFileChooser();
c.showSaveDialog(null);
}

public static void main(String [] args)
{
Test a = new Test();
a.init();
a.start();
}
}
