No buttons work on "Create A Poll"

I'm not sure what's happened, but I cannot create a new poll.  I've tried with all of my browsers, but when I get on the new poll page, although I can enter text into the fields, no button works.  I click away and the page doesn't move.  The browser recognizes that they are links, but that's about it.  Any thoughts on what could be happening?

Cheers,

Ian
