I've recently noticed that whenever you double-click an XPS file, it
opens in the default web browser, i.e. Mozilla Firefox. As there is no
Firefox plugin the browser than asks you to save the file.
Pretty amusing, I thought.
On checking the file association, .xps files are associated with "XPS
Viewer". Yet they open in Firefox anyway. :-)
Workaround is to bind them explicitly to IE, but IMO the XPS Viewer
should be a separate lightweight app, not sure why it isn't.
