FrontPage is an old application that's no longer supported, and due to it's age it's unable to recognise newer versions of IE.
I'm guessing you've updated IE from the version which ships with Windows 7 (IE8).
If you roll back to IE8 you shouldn't have that problem.
To roll back to IE8 you'll need to uninstall the IE updates (IE10 and/or IE9, depending on how many times you've updated it).
Control Panel > Programs & Features.
Click "View installed updates" in the left panel.
Scroll down to Windows Internet Explorer 10 (or 9).
Right-click >> Uninstall.
