*Symptoms:

Upon testing the supplied code I found that the problem occurs on
Solaris with JDK1.1.6 and AIX JDK1.1.6 but works OK on WinNT with JDK 1.1.6

The keyEvent methods e.g. isAltDown, isControlDown, isShiftDown
do not work, except on Windows platforms.

Applet and html provided below, I've also created an Application version.




*Test case:

//------------------------------------------------------------------------------------------------------------------------------------
// html file keyTest.html follows:
//
<APPLET CODE=keyTest.class WIDTH=350 HEIGHT=350>
</APPLET>


//------------------------------------------------------------------------------------------------------------------------------------

tf = new TextField(30);
tf.addKeyListener(this);
ta.addKeyListener(this);
// ta.setText("Hello");
// tf.setText("abcThere4567");
add(ta);
add(tf);
setBackground(Color.white);
