Trouble with AddThis widget

I noticed today that I can't use AddThis to share an image by email because when I'm typing in the AddThis window, Imgur's keyboard shortcuts remain active. This results in accidental upvotes, downvotes, and scrolling through images. Also, when the images scroll behind the AddThis box, it breaks the share. The link arrives as http://null/gallery/aBSSN rather than http://imgur.com/gallery/aBSSN. I'm using Chrome 19.0.1084.56 on a Windows 7 machine.
