    Description

      ReactOS 0.4.15-x86-dev (Build 20220314-0.4.15-dev-3900-gd3f3a97)
      (thanks to julenuri for indicating the executable: https://github.com/marciowb/Meus-Projetos/blob/master/componentes/DevExpress%20VCL/ExpressLibrary/cxLocalizerEditor.exe)

      When testing for the issue of missing black icons in toolbar- I found an unrelated issue (attached log)

      When [IntLinkHwnd / IntLinkWindow] fails with:

       

      (win32ss/user/ntuser/window.c:1030) err: IntLinkHwnd -- Trying to link window 0xBC65DAA0 to itself!!
      		 
      (win32ss/user/ntuser/window.c:927) err: IntLinkWindow -- Trying to link window 0xBC65DAA0 to itself!!

      The child window is rendered unrelaed to itself. But when you try to dismiss it, the deallocation page faults and it results in a BSOD:

      *** Fatal System Error: 0x00000050                       (0xFEEEFF36,0x00000000,0xF66FD4A5,0x00000000)

      You can reproduce it by clicking on the toolbar's down arrow to extend the options --> it shows "Add or Remove Buttons" --> when clicking outside the window --> BSOD

      (I'll try to find a tentative fix soon)
