  35  * 1. extend it to the wm_command and wm_syscommand notifications

  39  * 4. resolve the win9x case when there is a need or the testing frame work

  41  * 5. The test app creates a window, the user should not take the focus
  42  *    away during its short existence. I could do something to prevent that
