The OPI Web site uses iframe technology to embed information into some of our web pages. There is a well-known bug in internet Explorer 8 that the back button incorrectly focuses on the content of the iframe, rather than the expected behavior of focusing on the host page. We have been able to add a work-around to the Internet Explorer family of Web Browsers and have added the fix to our site.
double-clicking the back button will typically get you to the last page visited.
Modern web browsers* such as Chrome, FireFox, Opera and Safari for Windows and Macintosh do not experience this problem.
*Modern web browsers are defined as browsers that score at least 90% on the ACID3 Test
