Hello.
With Amaya 11 on Mac OS 10.4 PPC, I still experience an annoying drawback:
In an enclosed table in a table, the cursor seems stuck into the enclosed table.
Copy the following code to reproduce it.

<table border="1">
  <tbody>
    <tr>
      <td>one</td>
    </tr>
    <tr>
      <td>two</td>
    </tr>
    <tr>
      <td>three

        <p>here</p>

        <p>zgergzerg</p>

        <table border="3">
          <tbody>
            <tr>
              <td>one one</td>
            </tr>
            <tr>
              <td>two two</td>
            </tr>
            <tr>
              <td>3 3</td>
            </tr>
            <tr>
              <td>4 4</td>
            </tr>
          </tbody>
        </table>

        <p>end</p>

        <p></p>
      </td>
    </tr>
  </tbody>
</table>

Put the cursor in the word "here". Then navigate with left and right arrows, the behaviour is correct.
Then navigate with up and down arrow, the cursor moves to the inner table and can't leave it at the top.
Hope this help, Pascal.
