couple of CAPTCHA issues in 5.2.19 software

First, the text around the CAPTCHA field says:Spam prevention:
Please, enter the code that you see below in the input field. This is for blocking bots that try to post this form automatically. If the code is hard to read, then just try to guess it right. If you enter the wrong code, a new image is created and you get another chance to enter it right.

It will NEVER give a new code for the session. You have to abort the current PM and start a new one to get a new image no matter the number of failed attempts.

Second, our forum has a large number of older folks, retired, and I got the following complaint: Whoever designed it, forgot that many of the male populace are colour-blind. This makes the
subtleties of the code difficult or impossible to see . It is rue.

There are multiple captcha solutions to choose from. Select another one in the module settings for other output.

I'll do that tonight and report back.

The one that had the problems in the trouble report was the "code drawn using Javascript".
Code drawn using a gif image did not work at all, the image display box said "captcha" and the input field was too short.
Finally went with Code, plane text format, works (so far).

seems like reCaptcha is the only reliable (and friendly)? I have some bots that stills skip the other captchas
