KeyAdapter not getting input on JLabel when Frame maximized in windows

I have a JLabel that has a KeyAdapter attached to it that waits for
input, and when the user enters a specific string, it does something.
This works fine when the window isn't maximised, I can see the input in
System.out's that I added, but when I maximise the window, I can no
longer see that the JLabel is receiving the input. Could this be a bug
in the Windows JRE? I'm using Windows 2k and Java 1.4.2_11.

Looks like your label lost the focus.
Why do you use JLabel for user input instead of JTextField for example?

we're basically having them enter a sort of password to unlock a hidden
menu. using a text field would be too obvious.

Then javax.swing.JPasswordField.

I didn't even want to give the appearance that there was an option to
type something in. You had to be in the know. I finally chose a
JTextField and modified the Caret, Document, and Cursor to all be
hidden/not blink/etc., so it was completely transparent.
