So I'd like to get rid of the insecure warning I get in IE6-8 whenever I'm on an HTTPS page like this one:
https://checkout.netsuite.com/s.nl/c.659197/n.2/sc.37/.f?login=T&reset=T

I can't tell what's not loading, but I'm assuming the two errors I got in Companion.JS v0.5 in IE7 are clues:
1) 'jQuery' is undefined (line 6) (jquery.colorbox-min.js)
2) Object expected (line 266)

Any ideas?

Thank you!
