I can confirm there are sometimes problems with the output (on Firefox 
2.0.0.4). 1/4 of the time no recognizable character is shown.

Other notes:

I don't like the obstrusive Ajax feature at all (I use NoScript...): 
what's the benefit? Spammers trying to get around captcha can easily 
make an extra step and make XmlHTTPRequests too... From what I 
understand, there's at least a way to generate pure HTML, but I'd still 
like to understand why AJAX is an option.

I'm not sure why there are nested span in the captcha :

<span><span><span><span><span><span><span>&nbsp;</span></span></span></span></span></span></span>

?! Is it to accomodate rendering bugs?

There are &nbsp; in a <pre> with style='...,white-space:pre,... '. Seems 
the author *really* wants to be sure that spaces can not be rendered 
with newlines...
