[Plugin: WP-Syntax] Need to set the text for VB code in WP-syntax

Hi

I have a new site and I am using WP-syntax for the code display of our posts. I want to have all the code displayed in the same font…but I cannot get it to match the monospace font for the code.

I have modified the wp-syntas.css file and placed it in the right area but it does not seem to recognise it.

here is a URL of one post which is showing the code formatted by wp-syntax for VB….you can see that some of the words are in monospace and others are in a different font..

Any help appreciated
