Thank you for your post.
With Instant Web Publishing, the font sizes for Radio Buttons are generally larger. Size the column to be wider, and you should be able to see all three buttons. If the height of the field is impacted, change the height of each row to a larger size. This is done in Layout Mode under "Layouts -> Layout Setup..." Click the "Views" tab, click the "Properties" button for Table View, and at the bottom, check "Use custom height" and change from 14 pixels to 18 pixels. This handles most browsers.
