Try to update Silverlight to the latest version (5.1) and then test again.http://www.microsoft.com/getsilverlight/Get-Started/Install/Default.aspx

Thank you - the Silverlight update page flashes the banner "this page can only run in 32 bit" as the page appears unstable and crashes Firefox. My apology for the faq on Silverlight - I had seen the previous post but thought it applied to Netflix only.

Update - while Silverlight page was up and "only run in 32 bit" flashed and page jumped appearing unstable, I was able to get the update. Problem solved - thank you much. This community is.
