We have a website that uses "captcha" such that when the user completes a form, there is a 5 letter / number code that must be retyped.
All is done in php.
On Mac computers using Safari, the browser automatically uppercases the first letter of the response; since this DOES NOT produce a match, it fails. The customer does not realize what is happening.
Is there a way to either prevent that from happening or to force Captcha to upper case the first letter?
Note I have NO CONTROL over how users will have configured their browser.
The captcha modules is attached.
