Where can I fix this?

[RedGTiVR6]

I'm having an issue with long bits of code.

The [CODE ] [ /CODE ] tags are cropping the text if it is too long. There is a scrollbar on the bottom. Since the "yellow-ish" part extends the correct table width, I am not sure why there is a frame inside of it with a fixed width. Looks pretty bad IMHO.

Any ideas how to fix this?

I'm looking in the Style Manager -> Size and Dimensions but I'm not seeing anything.

Where else would I look to control the width of the scroll bar?
