When using Internet Explorer 8 you may need to enable Compatibility View.  You can access this setting in the address bar of your browser.
1.  Look for an icon that looks like a torn sheet of paper next to the reload and stop buttons.
2.  Press the Alt key on your keyboard so that the Internet Explorer menus appear.  (They are hidden by default)
3.  Click Compatibility View
If this does not fix the problem, please contact our Technical Support team at 662-349-9430.
