Issue importing xml text to Captivate

Hi guys,

I have used Javascript to import text from an xml document to a Captivate Text Caption box, This part works fine. However, when clicking on the buttons, the correct text shows but seem to get cut off (see image below). I have resized the caption box in captivate but this doesn't seem to do anything.

I

Javacsript called on Slide Enter

var myArray = new Object();
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.open("GET","CpFeatures.xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML; 
var x=xmlDoc.getElementsByTagName("entity");
for (i=0;i<x.length;i++)
  { 
  //alert(x.childNodes[0].nodeValue);
  var at = x.attributes;
  //myArray[at.getNamedItem("qu").value] = x.childNodes[0].nodeValue;
  myArray[i+1] = x.childNodes[0].nodeValue;
  }
window.cpAPIInterface.setVariableValue("FirstSetofOptions","Click on each tab to learn more about it.");

Javascript used to get first entity

window.cpAPIInterface.setVariableValue("FirstSetofOptions", window.myArray[1]);

Does anyone know how I can get all the xml imported text to show in the Captivate caption box? I have tried changing the Autosize Captions in the preferences to no avail.

Any help would be greatly appreciated.

Thanks
