I tried using 'Iwhatever' to no avail - the browser wouldn't even load the script. No error msg, nowt. Is it to do with the fact I put it in double quotes as the filepath has spaces in?? Yes I know it's naughty to have spaces in your filepath but I didn't set up the machine.

On the bright side we moved the whole lot from the test server to its production environment and it worked like a dream, without -I or anything else.

Thanks again Monks for the speedy help.
