[Been Told]

First of all: AWESOME Mod!!! This is something I've been looking for for ages!

Now here's a problem I'm having - I'll make an example:
I have disabled the COLOR BBCode (for testing purposes) for Usergroup A and enabled for Usergroup B.
Now a user in Usergroup A goes and types: [COLOR=Red]Test[/COLOR]
And when he looks at the post, that is just what he sees.
When a user in Usergroup B reads the post, he sees:
Test

That, of course, is not wanted. Am I doing something wrong?

I'm using vB 3.7 by the way.
