HWC HTML5 app open Email

Hi

I am trying to allow a user to create an Email using a hyperlink from a html page in a HWC app.

At present I have tried using the following:

<a href="javascript:hwc.showUrlInBrowser('mailto:test@test.com');">open email</a>

The app slides to the hwc browser but then leaves the hwc to open the email client.

My problem is that the hwc shuts down and locks when it leaves to open the email client.

When I return to the hwc it has closed all apps and is back at the initial screen.

Any ideas on how I can create a new email but return to the hwc at the state I left it?

Is this configurable?

Thanks

Andrew
