Hi Phil

Thanks for taking a look!  However, this script is running fine on a few
sites... Here's an example:

http://chrome.me.uk/shopdev/

It is running on a few other people's test sites... for the loop iteration I
use:

for (var i in Array) { // try this on, say, the document ;)
	alert(Array[i]);
}

Arrays in JS are associative (as they are in PHP etc.) so they key really
shouldn't matter... This just seems to empty the array for no reason

I've been using that prototype object for XHR for a while now

Any other hints or clues?

Cheers

Dan
