If you take a look at my profile, under the Posts tab one of my posts that i used the hide bbcode in causes a small issue to the IPB forum layout: it causes the post to jump out of its container. I made sure that this wasn't a browser specific issue (as i'm running the latest "unstable" snapshot of Opera) by viewing it in other browsers, and it does the same in Firefox. Though a small issue, i thought this should be pointed out anyway.
If it's alright with you, I turned the last HIDE code tag to QUOTE. This made your profile to show it correctly.Basically I'm going to blame on my unstable HIDE code where I slapped together from java and CSS from the IP.Board forum. So it's not written correctly and it's not stable for any IP.Board.
