CAPTCHA Input Case Sensitivity
Isn't the input to the CAPTCHA question suppose to be case sensitive? I created several forms, uploaded them to my website and as long as I have the correct letter and/or number combination and in order shown in the image, it always accepts the input, ignoring whether or not the letters are the proper case, i.e., upper- or lower-case. Any wrong letters or numbers, it does properly reject the input. I've uploaded the whole site each time just to make sure I don't miss a file.
Any comments on this behavior would be greatly appreciated. Thanks.
