Unfortunately, you didn't mention which version of Internet Explorer you're using, or the operating system... Either way, make sure you've updated you're version of Java, disabled any pop-up blockers, or possibly ad-blockers, which frequently prevent such buttons from working..
Hope this helps.

HI! I'm not newbie as such, but never came across this before and have no idea how to resolve it.
I'm trying to fill out an online application form, and before loading up it asked to run or install Silverlight (for some reason, there was no option to use Adobe Flash Player). Once I enabled Silverlight, the form loaded up fine, but one of the radio buttons is blanked out and I can't select it.
After playing about with different answers (country of origin etc.) from the drop down menus I've discovered that these radio buttons light up for some answers and not others. I don't get why, because the radio buttons I'm talking about are 'Print and post the form' and 'Submit the form online'. The former is the only active one. Phoned the company's local office; they have told me none of their other clients from the same location as myself have had this problem, and they might not be able to process the paper form. It has to be submitted online, and they insisted both options of submitting the form should be available to me.
It only lets you use Silverlight to open the form, I've reinstalled Silverlight in case the previous version was corrupt, switched between Mozilla Firefox and Internet Explorer- nothing helped. In fact, the form wouldn't even open in Mozilla. Could someone please tell me if there is a way of enabling these radio button or using an alternative to Silverlight to run the form? Also, if it's a possibility of any of my browser settings being wrong, what should I look at?
Many thanks in advance!!
