I've tried resetting plugins in IE7 and turning off the phishing-detection feature, with no success. I've also searched the Internet for solutions but couldn't any mention of this particular problem. Since it's IE7-specific, and IE is usually less strict than Firefox, I suspect the problem is not with my code. However, I'll attach a sample of the scripts in the head of my document and the links in the body.
Thanks for any help.
