radioButton Label Issue

I have given my radio button a label “Navigation with Frame Label” but the problem is that when I publish the swf the lower part of the text is cut which makes the text unreadable. I have tried out different things like changing the height of the radio button and using the
my_rb.setStylePropert(“textSize”,14) but nothing has worked so far so could you plz tell me how to go about it. One other thing is that I am using this swf as a custom UI in another fla component which make the appearance of the text even worse so kindly tell me some way around to over come this problem.
