Major issue: Can't post anything with new captcha!!!!!

You're captcha system isn't working properly. I cannot post anything with code in it.

It deletes every 3rd or so time, everything that I have written.

And now it asks for images, I click on them to verify I'm human, it says "you're human!" and just sits there, and does not post or change pages.

There is no support available for me while this is operating.

Chrome/win10/fibre/bl.

I've been posting in .xml files and uploading.

I've tried everything. Waiting, clicking fast. After clicking "Submit" it just takes me back to writing a new post with the blank editable region.

I find the error is only when I post code snippets though.

Inherently nothing can be posted with code in it.

Hi
This captcha system (presumably it's the same one) is also causing a major problem with registering on this forum as a new user.
I was not able to register at all using Firefox.
There is some erroneous HTML around where the captcha is loaded on the form, so at first I thought it was that, but actually Firefox had blocked the Shockwave plugin due to a security issue. This means the captcha doesn't load, but there's no indication of a problem, it just won't let you submit the registration form with a cryptic error message about not having played the game.
Eventually I was able to register using Safari.

Please please don't use something for a captcha that requires a third-party plugin that some systems may not even have! I've never seen another site that felt this was a good idea. I suggest using Google's "no captcha" reCaptcha - works well and only requires the user to click.

Sorry, not an ideal first post I know, but thought you ought to know this is probably preventing people from joining the site.

Cheers
Ben
