1. To see whether the object list updates correctly:
   Select a Sound and run the following script:
      Down to Matrix
      gfdjkghdfgj
   The object list may become visually empty when the error dialog appears,
   but should show up again when the error dialog is dismissed.
   If not, XmUpdateDisplay () may be incorrect or missing from error dismissal.

2. To see whether the queries in the sound window are responsive:
      Create Sound
      To TextGrid
      Edit together
      Get pitch
   The answer should be immediate, not wait for 3 to 7 seconds.
   If not, GuiWindow_drain () may be incorrect,
   or somebody replaced it with XmUpdateDisplay ().

3. To see whether the Info window updates with every text:
      echo Results:
      for i to 10
         for j to 10
            print   'j'
         endfor
         printline   'i'
      endfor
   If not, GuiWindow_drain () may be incorrect.
