Button Bug

Just come across a possible bug when using a converted text object with button states.
I've taken a piece of text and split it into individual characters so I can form a curved text line, Now group the characters into a shape or "object". From there I have turned the object into a button with "states" and "rollover". The button command works,and the rollover works but the main button only shows the first text character instead of the whole typed word. ("Enter" shows as "E", rollover shows as "Enter"). It's easy enough to get round the problem simply by copying the original and pasting it underneath the button, BUT¡¡¡. Cheers
