PDF in HWC

Hi,

I have a hyperlink to a PDF in one of my HTMLviews in my workflow screen. When I touch on this link (in iPad/iPhone), the HWC loads and render the PDF beautifully in its content pane. Now the issue is that I do not have a way to go back to the previous page. There is no back/cancel button. So practically this functionality is useless. Is there any way I could load the PDF in a new window? The target attribute of the A tag or the javascript window.open etc do not work in HWC. And none of the jquery mobile popups that I tried worked(most of the sample available on the Net requires a later version of jquerymobile than the 1.0 used in HWC. Please suggest a solution.

Thanks.
