Yes, this is Web Designer version 8.
The MX stands for Media eXchange. MAGIX and Xara are releasing a range of MX titles, which can easily interchange files via a new top Share menu. Xara Web Designer MX can exchange any graphic or photo with any other installed MAGIX MX application such as MAGIX Movie Edit Pro MX. More than that, the new Share menu also enables the easy sharing of files with other sites and applications, for example Web Designer MX offers one click upload of a selected photo or graphic to Flickr and Facebook via the Share menu.
