I'm trying to use a hyperlink button as a mailto in silverlight 4 like so:
<HyperlinkButton x:Name="hlbCustomerSupport" NavigateUri="mailto:[email protected]" Content="[email protected]"></HyperlinkButton>
and when I click it in the application I get:

I do this programatically elsewhere and it works. I tried the same approach for this one and still get the error.
I figured it out. The hyperlinkButton that works is in a child window (far nested control), the one that doesn't is in the site template (Child of the Application object). For this reason it appears that the hyperlinkbutton in the site template must have TargetName="_blank" specified. Not sure why this is.
