On Opera 8 for Windows, which masquerades as Internet Explorer by default, the CAPTCHA test doesn’t even work.
FEMA claims that the system was originally developed for in-house use only, and is working on a replacement system that will accomodate all popular browsers. This just goes to show, however that developers should embrace best practices wherever possible, even when building applications for limited deployment.
