Okay, cool, thank you. And to clarify, the mailto: link I created a few posts back exhibits the same behavior? If so, this pretty much confirms there isn’t an issue with the site, but with your handler of mailto: links.
I went through the setup process to enable GMail in Google Chrome to handle my mailto: links, and confirmed that this does work as expected on your site (opens a new e-mail message in GMail). I did have to remove GMail from the blocked sites list as stated in the instructions, not sure why that was there as I’ve never had Chrome as my default mail app at all, but it’s worth checking.
