What are the correct IE security settings?

To change your security settings in Internet Explorer, select Tools | Internet Option | Security. Make sure you have selected the Internet zone as shown on the picture below. Usually, the Medium security level is sufficient, and you can get to that setting by clicking the Default Level button.

You may encounter a situation in IE where the browser will sometimes show the Medium setting but will not actually use the proper settings for the Medium security level. In that case, click the Custom button and set each individual security setting as shown in the second picture below.

If you are still having trouble after using the Custom settings, double-check that you do not have any security or firewall that might interfere with ActiveX or Javascript. This includes utilities such as ZoneAlarm or Norton Internet Security.
