Er, yes, I get an error from the google analytics stuff ...erk

Failed to load resource: the server responded with a status of 404 not 
found  http://www.google-analytics.com/analytics.js

but this happens regardless, yet analytics is obviously working because 
I can see the daily totals and live view works perfectly ... oh jeez, 
this is becoming a mess ... but no, apart from the apparent anomalous 
analytics error I get nothing
