Bloody annoying

Made a post and put some 'code' in it.
Now I cannot edit that post without everything I type being that 'code' again.
But it's not even the 'code' I put in?

What gives?
Why is it doing it and how do I stop it?

code is nothing special....

Not sure if it's because I 'previewed' the post before posting?
I've managed to get around it this time by not previewing and typing the other stuff before posting.

Odd, I did quite some editing/previewing and used allot of different formatting (wiki section for example) and never had any problems.
