Arial specified in CSS breaks site in IE9

Question

I've only seen this issue in IE9 and only on certain PCs. In my CSS I have the following, which sometimes causes a blank page:

font-family: Arial, Verdana, Helvetica, sans-serif;

If I change the CSS to this then the page loads, but Arial is not used for the font:

font-family: "Arial, Verdana, Helvetica, sans-serif";

Answer 1

Try:

font-family: "Arial", "Verdana", "Helvetica", "sans-serif";
