Forms acting as links?

Hi,

This is 90% likely my fault, but I’d like to rule that out and possibly get your input.

Drop-down and text forms, when clicked, bring me back to the website’s index.

I initially mistook this for a fault with a plugin that generated a drop-down form on my homepage, and the developer tells me this is the work of a piece of JavaScript.

Any ideas?

Cheers for the awesome theme.
