EnumWin:

Delphi-Quellcode:

  if szClass = 'Notepad' then 
  begin 
    Win := PWinInfo(GetWindowLong(Handle, GWL_USERDATA)); 
    { set back ptr } 
    SetWindowLong(Handle, GWL_WNDPROC, Win^.OldPtr); 
    { free memory } 
    Dispose(Win); 
  end;

I see the problem within Dispose(). Dispose uses the memory manager of the calling process. But your Hook-Dll is executed in many processes. So what you do in this code is freeing memory not allocated by this process.
