I have problems with the Captcha ant-spam filter.  The encoded check word letters are very indistinct in pale colours and very difficult to decipher what letters are intended.  Furthermore, if a visitor to the site has already entered all mandatory details and his message and then finds the Captcha check word was wrong and resets the check word, the website deletes all of his information so that he must enter it all again.  This is most frustrating for site visitors.  Is there something I can do to get more distinct Captcha check word display or something WX5 can do?
