Silverlight and Firefox Visibility Issue

Question

Hi

I have a web application that has a div with a silverlight control inside of it. The div initially has a style of display: none. I have a button that sets the div's style to '', to show the div and the silverlight application. This works fine in IE. But in Firefox it just shows a white box. Doing a little javascript debugging, it appears that the silverlight control is never even loaded.

Any idea what the problem is and how to fix it?

Thanks
