FULL PRODUCT VERSION :
java version "1.4.1_01"
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 :Windows NT Version 4.0


A DESCRIPTION OF THE PROBLEM :
Top Level frames need to have the ability to set OUTLINE DRAGGING on and off. OUTLINE DRAGGING is currently only available with the Windows L&F.

If one wants to use their own L&F with JFrame.setDefaultLookAndFeelDecorated(true) then there is no way to set OUTLINE DRAGGING. These can cause performance issues when resizing the JFrame as it is
continually repainted.

A good description of the problem with a code example can be found in the Project Swing forum.
