    <p>On an older, slower computer system, I was able to reproduce the
      error displayed in w2web as:</p>
    <p><b>System Error</b></p>
    <p>Couldn't write to /.</p>
    <p><u>back to last page</u><br>
    </p>
    <p>To produce the error, what I did in w2web was 1) I clicked the
      "view case.outputd and cp case.in0_std case.in0" button, 2) paused
      about 5 seconds, and 3) clicked the "Save and initlapw" button.</p>
    <p>The file size of the case.outputd is 43.6 MB.  I suspect the
      error results because my computer is slow in opening the
      case.outputd file where I clicked on the save button before the
      file got opened up.</p>
    <p>When I clicked "view case.klist" followed by clicking as fast as
      possible "Save and initlapw", I do not encounter the same error. 
      The file size of case.klist, however, is only 101 bytes.</p>
    <p>I also 1) clicked the "view case.outputd and cp case.in0_std
      case.in0" button, 2) paused about 1 minute, and 3) clicked the
      "Save and initlapw" button.  When doing that, the error did not
      occur.<br>
    </p>
    <p>I put the 43.6 MB case.outputd on a new faster computer system
      clicking the "Save and initlapw" button immediately after having
      clicked the "view case.outputd and cp case.in0_std case.in0"
      button and the error do not appear.</p>
    <p>From that, it seems to be a computer system resource limitation
      that is causing the error.</p>
    <p>Kind Regards,</p>
