When I move an icon on desktop over message dialogue, Windows does not
work any more.

1. Reproducing
 
 1) Compile the attached sample code
 2) Invoke "java test"
    -> You can see a Frame which inculdes file tree and "OPEN" button.
 3) click the "OPEN" button
    -> you will see a modal message dialogue.
 4) Drag an icon on the desktop and Move it over the dialogue of 3)
    -> you will see Windows become freeze.
    
    We can do "alt"+"ctl"+"delete" and kill the above process for recovery.

2. Sample Code

   Please see the attached file

3. Configration

  MPU : Pentium 1.4 [GHz]
  Mem : 384[MHz]
  OS : Windows 2000 (SP2, Japanese)
  JDK : 1.4.0fcs

4. Note
  
  This behavior looks regression.
  When I tried the above reproducing process with 1.3.1_03,
  the icon returns to the desktop and the freeze does not happens.
