FULL PRODUCT VERSION :
1.6.0_16

ADDITIONAL OS VERSION INFORMATION :
Windows XP SP2

A DESCRIPTION OF THE PROBLEM :
Create two or more frame windows. Display a modal dialog using
one of the frame windows as a parent.

All frame windows will be blocked.


This problem appeared when I upgraded from 1.5 to 1.6. A previous bug was reported for this same issue (4080029) but was fixed in a previous release (mustang b38)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1) Create a Frame with a button inside that will make a Dialog visible when clicked
2) Create a second frame with a button inside that will display a msg to standard out
3) Now run test program and you will see two frames
4) Click on frame 2 to verify the standard out is displayed
5) Click on frame 1 to display the dialog
6) Now goto frame 2 and click button. Note that the messages wont display until dialog is closed.


ACTUAL -
  From frame 1 click button to display modal dialog
A dialog is created and is visible
Set focus to other frame window and click button inside
No output displayed from clicking button

REPRODUCIBILITY :
This bug can be reproduced always.
