[3.0.x] BBCodes and WYSYWIG editor

[BadFurDay]

I'm sure this question has already been asked, but I searched and didn't manage to find an answer to it.

I added plenty of custom BBCodes to both of my forums, for various necessary reasons, and added previews to them for the WYSYWIG editor (when replying to posts).

In the forum I run on vBulletin 3.5.x, I found a solution, but for the one I run on 3.0.x, I didn't manage to find any: The preview images for the bbcode are just making the editor's toolbar larger and larger and are not skipping a line (as in, making a linebreak, I don't know the exact word) when necessary. How can I fix that? (if I'm not clear, I can provide a screenshot of the my issue).


Thanks in advance everyone!
