This is all very nice -- and it's good to see the Oxford Text Archive getting a name-check. But why would I use this widget when it's only compatible with Mac OS 10.4 and, in that operating system, I can simply hover the cursor over a word, type command-control-d, and get an Oxford Dictionary pop-up containing at least the information offer by this widget?

Possible answers: I want British English (Mac OS' Oxford Dictionary is American); command-control-d does not work in all apps (but then I could just fire up the Dictionary application). But anyway...

The installation procedure is way too involved, especially for us pampered Mac users. (I initially fell at around the third fence, but did manage it eventually.) To find anything like a wide audience, the widget must be rewritten so that, on first use, it scripts Safari to open up the registration page, pops up instructions on what to do, and waits for the right file to appear in the Safari's download folder before proceeding with automatic installation.
