Where to change the font for Checkout with PayPal on the Checkout Payment Page

Hi,

I have changed the default font for my whole site and it works fine except for the Checkout with PayPal text on the Checkout Payment page.

Looking at the view source, there is

Code:

---

<span style="font-size:11px; font-family: Arial, Verdana;"> Checkout with PayPal</span>

---

only on this line and not an any of the other lines.

Looking at the tpl_checkout_payment_default.php page I can find all of the code for that page except the span that is in the PayPal one, so I figure that this is lurking in another page.

Can someone tell me where can I find this?

Thank you for your time
