/*

1) Run the test program below, on the first go
everything works fine.

On second and subsequent attempts (ie user types
bad password on the first try) the JPasswordField
works fine if a mouse click is used to put focus
into the Password: field.  If the user hits <TAB>,
focus moves to the Password: field, but the cursor
lands in the middle.  If you go enter some text
and click [OK] anyway, the getPassword() method
returns an empty string.

I don't thinks it likes the setText("") call to
clear the field.  Unfortunately i cannot find
another way to clear the existing field.

3) No errors reported, it just didn't work

4) As above

5) Occurs on Window NT4.0SP3, tried different look & feels all with
the same result Roughly the same code works with previous Swing
releases
