Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)


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

EXTRA RELEVANT SYSTEM CONFIGURATION :
Multi screen system, 3 screens:
Screen 1: Barco 8 bit static grayscale
Screen 2: Barco 8 bit static grayscale
Screen 3: Matrox 32 bit color.

Primary monitor is Screen 3.

A DESCRIPTION OF THE PROBLEM :
In a system that is set up as above, put the primary
monitor on the right through Windows Display Settings. This
will make the origin (0,0) correspond to the top left
corner of the rightmost monitor, and the other monitors on
the left will have negative co-ordinates ( (-2400,0), (-
1200, 0) in this case).

In such a scenario, any JDialog/JWindow that is positioned
on the non-primary monitors will not catch mouseEntered and
mouseExited events at all. The same JDialog/JWindow
positioned on the primary monitor, will catch all events.
However, mouseClicked events are caught consistently.

Attached is a simple program to reproduce this.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Set up the system as above, make sure the primary
monitor is on the right.
2. Position a dialog on any of the monitors and listen for
mouseEntered or mouseExited events.


REPRODUCIBILITY :
This bug can be reproduced always.
