326760 SSL/help needed

We have huge problems since we installed EV-SSl certificates. Registration page (https) takes very much time to load, approx 2-4 minutes.... Strange enough we had until today an alert about " page contains unsecure items etc" ...But all links were HTTPS. Strange enough, this alert did not appear in FF...... Now the alert is gone, because it seemed that Clickyanalytics caused this problem. We delete the clicky code, and the alert is disappeared.... But something is defintately not ok: !. Why are those pages loading so slow? This has to be solved. 2. How is it possible that analytics code can give the problem, and how can we make clicky work on those pages... 3. Why is the IE8 not giving the green color (as save website)? So this is about EV SSL.
