Ok this error was also reproducible on python:

http://vtk.org/pipermail/vtkusers/2004-January/021857.html [^]

ello,
I have updated my vtkWin32OpenGLRenderWindow (lines where not the same at all). My app doesn\'t crash anymore but I have a VTK error instead :

wglMakeCurrent failed in MakeCurrent(), error: Invalid descriptor
wglMakeCurrent failed in Clean(), error: 6

Here is the location :

void vtkWin32OpenGLRenderWindow::MakeCurrent()
{
  // Try to avoid doing anything (for performance).
  HGLRC current = wglGetCurrentContext();
  if (this->ContextId != current)
    {
    if(this->IsPicking && current)
      {
      vtkErrorMacro(\"Attempting to call MakeCurrent for a different window\"
                    \" than the one doing the picking, this can causes crashes\"
                    \" and/or bad pick results\");
      }
    else
      {
      if (wglMakeCurrent(this->DeviceContext, this->ContextId) != TRUE)
        {
        LPVOID lpMsgBuf;
        ::FormatMessage(
          FORMAT_MESSAGE_ALLOCATE_BUFFER |
          FORMAT_MESSAGE_FROM_SYSTEM |
          FORMAT_MESSAGE_IGNORE_INSERTS,
          NULL,
          GetLastError(),
          MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language
          (LPTSTR) &lpMsgBuf,
          0,
          NULL
          );
        vtkErrorMacro(\"wglMakeCurrent failed in MakeCurrent(), error: \"
                      << (LPCTSTR)lpMsgBuf);
        ::LocalFree( lpMsgBuf );
        }
      }
    }
}

called in vtkWin32OpenGLRenderWindow::Clean()

    if (wglMakeCurrent(NULL, NULL) != TRUE)
      {
      vtkErrorMacro(\"wglMakeCurrent failed in Clean(), error: \" << GetLastError());
      }

Does the problem still occur with VTK 5.10 ? VTK 6 ?
