Captcha problems

Just an FYI - Not sure if anyone else has had this issue but I’ve been having some weird captcha failures recently. When I try to log on it will give the green tick and then when I click the login button will say the captcha failed - and do that for a few times. When it’s happened I just give it a few minutes or come back a bit later and it’s worked fine then.

Not sure if it’s me, my PC, or the captcha system.

Did you click all the squares with traffic lights?

And the bicycles, and the fire hydrants, and the cars, and the buses! Nada.

you probably missed the one where the traffic light is one micron into the next square
