Browser closes when attempting to checkout

Some software plugins to your web browser may cause the browser to close or have other failures when you attempt to proceed to checkout. For example, customers who use Internet Explorer version 6 or 7 and have RealPlayer version installed on their computer will experience this problem due to a security flaw in that version of RealPlayer. To fix this problem, just update the RealPlayer version installed on your computer (within the RealPlayer application, go to Help--About RealPlayer and click the Check For Update button).
