Problems when copying XML

Hi,
When I am copying the XML from the forum ,the process window is not displaying operator diagrams in RM5.
For example.


<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.0">
  <context>
    <input/>
    <output/>
    <macros/>
  </context>
  <operator activated="true" class="process" expanded="true" name="Root">
    <description>Using a logistic regression learner for a classification task of numerical data.</description>
    <process expanded="true" height="584" width="962">
      <operator activated="true" class="retrieve" expanded="true" height="60" name="Retrieve" width="90" x="45" y="30">
        <parameter key="repository_entry" value="../../data/Sonar"/>
      </operator>
      <operator activated="true" class="logistic_regression" expanded="true" height="94" name="MyKLRLearner" width="90" x="179" y="30">
        <parameter key="calculate_weights" value="false"/>
        <parameter key="return_optimization_performance" value="false"/>
      </operator>
      <operator activated="true" class="apply_model" expanded="true" height="76" name="Apply Model" width="90" x="431" y="28">
        <list key="application_parameters"/>
      </operator>
      <connect from_op="Retrieve" from_port="output" to_op="MyKLRLearner" to_port="training set"/>
      <connect from_op="MyKLRLearner" from_port="model" to_op="Apply Model" to_port="model"/>
      <connect from_op="MyKLRLearner" from_port="exampleSet" to_op="Apply Model" to_port="unlabelled data"/>
      <connect from_op="Apply Model" from_port="labelled data" to_port="result 2"/>
      <connect from_op="Apply Model" from_port="model" to_port="result 1"/>
      <portSpacing port="source_input 1" spacing="0"/>
      <portSpacing port="sink_result 1" spacing="0"/>
      <portSpacing port="sink_result 2" spacing="0"/>
      <portSpacing port="sink_result 3" spacing="0"/>
    </process>
  </operator>
</process>

Thanks
