Clyde,
Unfortunately the captcha using TFF breaks my cart. I tried it on two separate carts, and I get the same results...when trying to log in or create an account, white blank pages. I tried to win merge them, but some of the pages are SO different, I didn't really know what should be changed.

I had to go back to the other captcha in the downloads section: captcha anti robot registration.

I did install the zip files you included for the other captcha (tff one) in a previous post to see if they would add a captcha to my testimonials page, but all I get is a
Code:
Verification code: Enable this picture
Redraw Capture Image
Verification code:  * (case insensitive)
But no picture shows up.

I know my captcha doesn't have the redraw button (a HUGE drawback in my opinion), you have to refresh the page to get it to redraw, so I am assuming the zips you supplied won't work.

Any suggestions? (beside learning to use winmerge )?
