Captions not displaying properly in IE7

Hi,

Captions in my gallery look fine in Firefox and IE v6, that is they are to the right of the photo and the text is left justified. But in IE v7, the text is not left justified and the last few characters are being chopped off on the right.

Does anyone know what is going on here?

Here is a sample page:

Thank you in advance,
Mark
