Resolution

Add the following additional style definition in wiki.css

  pre {
  background:#FFFAF2;
  border:solid 1px #6A4E22;
  overflow:auto;
  padding:4px 4px 4px 0;
  }

Problem

A long text line in a <pre> block is not entirely visible as the borders obscure the right end of the text. A scroll bar should be activated if the the <pre> block exceeds the size of the main body.

Example

    <!-- Namespace providers are responsible for storing the information in FlexWiki topics. 
         Namespaces can be stored in the filesystem or in SQL Server. It is generally better 
         not to edit this section by hand. Use the administrative tools located at /admin
         off the wiki root URL instead. -->
    <NamespaceProviders>
      <!-- A sample provider that stores a wiki namespace called SampleNamespaceOne in the filesystem 
          in the directory Namespaces\SampleNamespaceOne (relative to the directory where FlexWiki 
          is installed). Note that the ID must be unique amongst all providers. -->
      <Provider Id="5a2caaff-c139-40ad-85df-cdf136c95458" Type="FlexWiki.FileSystemNamespaceProvider" AssemblyName="FlexWiki">
        <Parameters>
          <Parameter Name="Namespace" Value="SampleNamespaceOne" />
          <Parameter Name="Root" Value="Namespaces\SampleNamespaceOne" />
        </Parameters>
      </Provider>


      <!-- A second sample provider. -->

          <Parameter Name="Root" Value="Namespaces\SampleNamespaceTwo" />
        </Parameters>
