Giant Type

Ok, I am frustrated. For some reason I cannot get the type size on this to change. The only thing it will let me do is type in this size. Normally you just go up to the little size clicker and it drops down and you click on the size you want. I like small. No matter how many times I have clicked and switched it will not let me change the type size. I mean I can't change to small, I can't change to giant, I can't change it period. I do not like this giant type. I have never had this happen before. I have not blogged in almost a week. Did something change? I keep trying to click on the type size, it slides down I click on "small" and nothing changes. What is going on here?
