It shouldn't; we haven't changed the template. However, some viewers no longer see the white box around the text, and are trying to read it overlaid against the background.
This is probably a browser conflict related to Internet Exploder and the aging template I'm using. One possible solution: Toggling the compatibility view (via the Tools menu) in IE.
When I have the time, I'll try to update the template to a more current version, but that is a tedious task as it will lose all my customization.
