Description
Name: rmT116609			Date: 08/27/2002


FULL PRODUCT VERSION :
java version "1.4.1-rc"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-rc-b19)
Java HotSpot(TM) Client VM (build 1.4.1-rc-b19, mixed mode)

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

A DESCRIPTION OF THE PROBLEM :
An undecorated jframe (frame.setUndecorated(true)) when maximized covers the windows taskbar, even if i selected the always on top option. this doesn't happens for decorated frames.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. open the metalworks jfc demo using jdk 1.4.1 rc
2. maximize the window using the top right buttons
3.

EXPECTED VERSUS ACTUAL BEHAVIOR :
the taskbar should be covered only if i disabled the "always on top" windows setting (to select this option right click on the taskbar and select properties)


The problem is not reproducible with JDK1.3.1_04.

REPRODUCIBILITY :
This bug can be reproduced always.

Release Regression From : 1.3.1_04
The above release value was the last known release where this 
bug was known to work. Since then there has been a regression.

Comments
Test case java/awt/Toolkit/ScreenInsetsTest/ScreenInsetsTest.java is amended to work taking into account existence of this bug. When this bug is fixed the test case needs to be updated again.

EVALUATION This is not a regression since undecorated frames is new to 1.4. They always cover the taskbar no matter the windows taskbar setting. We should probably respect this property. ###@###.### 2002-08-28
