Caching captchas?

Hi!

It seems that captcha generated by Yii (in default, auto-generated by yiic contact form of a base application) is somehow being cached. I don’t know how and why, since both auto-generated application and my own project does not use any caching component. But the fact is that I’m having generated captcha code (text) changed after a few times refreshing page or after few e-mails sent. Not after every one - as I would expect.

Is there anyway to prevent it? I.e.: to have new captcha code generated each time user visits contact form (or re-visits it after sending e-mail)?

Thanks in advance,

Trejder
