Player view is changed when pressing the button at ANYTIME

My "Change Perspective" option is changed to R and everytime I press it changes my view. But it also changes it when I press it when im chatting or doing commands. It doesn't matter what im using in minecraft. If I press that button it changes my view! Its SO annoying! This happened after I got the 1.2 beta and its still there! This also happens with ANY button you selected for the option.
