We finally give up ... we cannot support Internet Explorer 8 or any IE older than that any more. We are very sorry but IE8 does not have the capability to support functions necessary to create mobile device and PC capable responsive websites. I guess soon we will not be supporting IE9 or even 10 but for now IE8 is off the list.
Note:
Beginning January 12, 2016, only the most current version of Internet Explorer available for a supported operating system will receive technical supports and security updates. Internet Explorer 11 is the last version of Internet Explorer, and will continue to receive security updates, compatibility fixes, and technical support on Windows 7, Windows 8.1, and Windows 10.
