FULL PRODUCT VERSION :
java version "1.4.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-
b21)
Java HotSpot(TM) Client VM (build 1.4.1-b21, mixed mode)

FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version
5.00.2195]
Service Pack 3

A DESCRIPTION OF THE PROBLEM :
If I select a JMenu and click afterwards on a component, for example a
button, this component doesn't get the focus.

This is strange,
because the button looks a short time like it was pressed.
If you try the
same with a textfield, you get first an "Input"-Mousecursor while moving
the mouse over the textfield, but clicking on it does nothing.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Start the example
2. Click on the first texfield
3. Click on the
menu
4. Click on the second textfield / button

EXPECTED VERSUS ACTUAL BEHAVIOR :
What I expected: Clicked components gain focus (if focusable) and
buttons fire actions.

What happens: The component which was focused
before the menu was selected is focused again.

Seems it has something
to do with the new Focusmanager and temporary FocusEvents, even though I
didn't tested it.


REPRODUCIBILITY :
This bug can be reproduced always.
