      Description

      Name: rmT116609 Date: 05/20/2004


      FULL PRODUCT VERSION :
      ava version "1.5.0-beta"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta-b32c)
      Java HotSpot(TM) Client VM (build 1.5.0-beta-b32c, mixed mode)


      ADDITIONAL OS VERSION INFORMATION :
      Linux MyLaptop 2.4.18-14 #1 Wed Sep 4 13:35:50 EDT 2002 i686 i686 i386 GNU/Linux

      EXTRA RELEVANT SYSTEM CONFIGURATION :
      using XWin/gimp with 8 user selectable/switchable panels.

      A DESCRIPTION OF THE PROBLEM :
      the new Window( Frame ) does not disappear ( hide(), setVisible(false) ) when I select a different X Windows Gimp Panel to work on. A windown with a Frame() disappears when i context switch between gimp panels. But the Window(Frame) is painted on each of the Gimp Panels.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      run program.
      Select the "press this button" painted on the top left of the screen
      a row of buttons will be painted at location(200,200);

      Now switch working Gimp panels. The press this button disappears. The row of 10 buttons appear on each of the gimp panels.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      At first I though I had to do something to catch a Window event, and do something appropriate. But I saw that 1.4, and 1.3 both java panels disappeared when I context switched between gimp panels.

      Now I expect that both java panels should have disappeared.

      REPRODUCIBILITY :
      This bug can be reproduced always.
