It seems that this started when the maps became "bing" maps. Is there some resolution to this within your site so that users don't have to change the security setting in Internet Explorer? I don't get this in Firefox, but most of our clients probably use Internet Explorer. I don't want them to get frustrated by seeing this message over and over.This page contains both secure and nonsecure items.
Do you want to display the nonsecure items?
Can you resolve this issue?
