                          &nbsp;&nbsp; between the files is the number of
                          timesteps contained in each of them.<br>
                          <br>

                          &nbsp;&nbsp;&nbsp; These files contain 2 and 1 timesteps
                          respectively, but their structure is exactly
                          the same <br>

                          <br>

                          2.5.2) can <br>
                          &nbsp;&nbsp;&nbsp; correctly open all the files. Therefore I
                          suspect that the problem is somewhere in the
                          bridge <br>
                          &nbsp;&nbsp;&nbsp; from VisIt to Paraview of the two most
                          recent releases. <br>
