Code tag doesnt work properly?

[Finger78]

I'm trying to make posts that has some tutorials on sig usage etc on my forums and when I put the code I want within the [ CODE ] (spaces intentional) I can only enter in the opening code within that or else it completes the code if I enter in the close tag as well.

Example - when I type

[img]img url here[/img]

it completes the img code even thought its within the code tags so I'm forced to leave out the close code for it to show up, so mine has to look like this:

[img]img url here

If I put the close tags in my within the CODE tags I just get a blank code box.

Does anyone know how to get ALL of the code to work within the CODE tags?

I'm on vB 3.6.5
