A JButton inside a JFrame has the action to print a message to the java console
when the button is clicked. This code is in an applet.
The applet is launched. Another window is brought up, such as WordPad, and that
window partially obscures the browser underneath but the button is still visible.
If the button is clicked, it only intermittently will print the message to the console.
Mostly the button click will bring focus to the browser and pop it to the top but no message will print.

This problem occurs on Windows XP and Vista, with either IE 6, 7 or Firefox,
