When users are going through squid there are certain pages, like the one I mentioned where you just can't click a specific button. It always seems flash related. If I reconfigure this user to not use squid I can use the page just fine. This leads me to believe its not solely a browser issue. When I say I told it to ignore I meant in the squid.conf file, where I allowed access to that specific domain without any kind of authentication. Thinking about it, I understand this step is pretty pointless as squid still processes the site. However I have had success in the past by allowing access to sites before the proxy_auth required command. Not really sure what the issue is, but it seems to happen with just a handful of random sites.
