FULL PRODUCT VERSION :
java version "1.4.0-beta3"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta3-b84)
Java HotSpot(TM) Client VM (build 1.4.0-beta3-b84, mixed mode)


A DESCRIPTION OF THE PROBLEM :
Buttons in nested JInternalFrames do not work the first time they are clicked. Rather the buttons require multiple
clicks depending on how deep the internal frames are nested. For example, for an internal frame within one
internal frame, I need to click a button twice in order to actvate the "actionPerformed". If I add another nested
internal frame, I need to click the button 3 times, etc.

This bug is in 1.4.0-beta3 but not in 1.3.1.

REGRESSION. Last worked in version 1.3.1

The problem is reproducible on Windows 2000, Solaris 2.8, Linux Redhat 6.1 using 1.4.0-beta3.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.Run the attached program (there are 2 classes).
2.Click the button "Add Nested Frame"
3.In the nested frame, click the button "Add Nested Frame"
4. etc.


EXPECTED VERSUS ACTUAL BEHAVIOR :
The button requires progressively more clicks in order to invoke the "actionPerformed" - which is not what one expects.

This bug can be reproduced always.
