I had a look at your site and everything looks normal, I think.
The text looks smaller (maybe you've just set the font size to 8pt?)
I'm using IE7.

You can also try this in your css file:

'// declare a default font-size
body {...font-size: 9pt;....}

'// override that size in the specified tags
span.ContentText {...font-size: 10pt;....}

This should do it!
