JQuery UI 1.8.5 dialog - now has scrollbar since upgrade

JQuery UI 1.8.5 dialog - now has scrollbar since upgrade

Hi
I upgraded from 1.8.4 to 1.8.5 and this has caused my dialog to display with a scroll bar.  The only change is which version of jquery-ui.js file I am linking to.

This is the html for the dialog:
<div id="myDialog" title="My Title"><p>This text forms the first paragraph of my dialog text. Lorem Ispum blah test.</p><p>This is the second paragraph text of my dialog.</p></div>
This is the code for showing it: 
var dlgOpts = {
  bgiframe: true,
  modal: true,
  closeText: "Ok" ,
  buttons: {Ok: function() {$(this).dialog('close');}}
};
$("myDialog").dialog(dlgOpts);





Using 1.8.4 both paragraphs display without scrolling

but with 1.8.5 it displays with a vertical scrollbar with only the first part of the first paragraph showing:



This is using IE6 standards mode (no I do not have a choice!).  It is ok in IE7 and IE8 but a lot of the users are stuck with IE6 so it needs to work there as well  It is ok in the demo but I suspect that is because my page is using a larger font throughout.

The exact wording to displayed in the dialog is going to be configurable (added to the div tag when the page is generated) so I'd rather not have to specify a height as I would have to calculate it first.

So for the time being I'm going to stay with version 1.8.4
