SCode plugin and CAPTCHA provider?

Answer: I have 2 problems.

1) The old Comments Listing Template is just not showing up. Though I still see the Comments Preview Template and I got that one to work for single post preview mode.

2) Gotta replace the SCode MTSecurityCode and MTSecurityImage tags with new tags added to MT4.
I think SCode (or at least an earlier version of it) does not work with MT 4.261. Instead I copied this code snippet below over the SCode snippet in the Comments Preview Template:

Then I went into Preferences | Comment | CAPTCHA Provider and set it to "MovableType default". That seems to make CAPTCHA work again for single post previews at least.

Okay, the XML gets eaten up. See here:

This is what you use to replace the SCode MTSecurityCode and MTSecurityImage:

<MTIfNonEmpty tag="MTCaptchaFields">

<MTIfCommentsAccepted>

<MTIfRegistrationAllowed>

<MTElse><$MTCaptchaFields$>

</MTIfRegistrationAllowed>

</MTIfCommentsAccepted>

<div id="comments-open-captcha">

</div>

</MTIfNonEmpty>
