[Plugin: Contact Form 7] Drop-down menu looks strange

Hi there –

I seem to be having trouble with the drop-down menu function of Contact Form 7.

Here’s the page… scroll down to the bottom to see what I’m talking about.

Shouldn’t the drop-down actually DROP-DOWN, rather than showing up in a scroll-type box? How do I make it look normal? Is this a CSS thing from my theme or something with the plugin itself?

Thanks in advance,
Cynthia
