[Plugin: Contact Form 7] captcha and textarea alignment

I’m setting up a contact form using contact form 7 and the really simple captcha plugin, and I cannot figure out what’s going on. The captcha image and the captcha teaxtarea input field won’t line up vertically. It pushes the textarea field down a line.

Here’s what it looks like on the site:

Contact Form

It’s got me stumped. I’m not sure if it’s a code issue with the plugin or an issue with my css. Any thoughts or help is appreciated. Thanks!
