Hello,

I wanted to report a strange working of Captcha... sometimes Captcha does not accept correctly entered text. I have noticed that it happens when there is an overlap of characters. Below I'll post screenshots I took here on MyBB.com and from my GimpForums.com, where I have custom fonts installed.

Try it yourself! Thanks

Hmm.

I'd say that said CXLJL (I know it says CX1JL in the picture). Didn't accept that, viewed the image directly:

CLJLX, accepted that.

The X showed second in one image but fifth in another; if you view a CAPTCHA image directly it'll show the same text in different colours/fonts etc.

Will try and reproduce on my localhost at some point.
