FULL PRODUCT VERSION :
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)

FULL OS VERSION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
When a modal dialog is opened from a non-modal frame, key events are not sent to the modal dialog, they are instead sent to the inactive frame.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1) Run attached program.
2) Click the button labeled "Open second screen"
3) A dialog with a single button will appear
4) Try hitting the Enter key to trigger the default action - the Enter key is sent back to the inactive window
5) Try hitting the hot key combination for the button - this, too, is sent back to the inactive window
6) Try hitting the hot key combinations for the buttons on the first window - they work even though that window is not active


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
KeyEvents will go to the active window
ACTUAL -
KeyEvents go to the inactive window

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
If the button on the modal dialog is focusable, this problem won't occur.
