Doing a thread necromancy here as I was looking for a solution to this myself and figured something out just now

Make radiobutton id=13 a hidden button e.g.

Code:

<visible allowhiddenfocus="true">false</visible>

Then use another button to set it like so:

Code:

<control type="button" id="9013">
    <label>Auto-Update</label>
    <onclick>SetFocus(13)</onclick>
    <onclick>Action(Select)</onclick>
    <onclick>SetFocus(9013)</onclick>
    <visible>Control.IsEnabled(13)</visible>
</control>

Thanks jurialmunkey, I was able to get the dialog just the way I want using this.
