Attached are two screen shots. Rivermont 2 is how the screen should look with the Home, About US, ... active links
Rivermont 1 is how the screen looked after changing the font in Windows 7 and then changing it back to the original setting. The words across the first row are now active but the second row no longer is. the screen has been compressed.
All the settings were the same for both screen shots except that Rivermont 1 was taken after Windows 7 fonts were increased in size and then returned to their original setting.

Thanks for your interest in this problem
