Subscribe2 Widget won't work with Chrome

I use the Subscribe2 plugin and have the subscription widget. It was working fine but suddenly the widget won’t work in Chrome. You can’t click in the box to enter your email address. The buttons also are not clickable. IE and Firefox are fine. I tried Chrome from a couple different PCs in case it was an issue with my Chrome install but no luck. Any ideas?
