This issue is the same regardless of browser or OS. It's a board issue, and whether the person posting utilizes the boards built in codes properly. If someone places a backslash in the wrong place, it'll come up messed up no matter what you're using. And if tags are placed in the appropriate place, it'll come up fine.
“You know the world is going crazy when the best rapper is a white guy, the best golfer is a black guy, the tallest guy in the NBA is Chinese, the Swiss hold the America's Cup, France is accusing the U.S. of arrogance, Germany doesn't want to go to war, and the three most powerful men in America are named "Bush", "Dick", and "Colin." Need I say more?” - Chris Rock
