Jay,

Let's see if I get your classes right;

*
                              MyButtonClass
                                    |
                                    |
                                    V
                              MyTextButtonClass
                                    |
                                    |
                                    V
                              MyPictureButtonClass

Is this correct? If it is may I suggest a change ion the class structure to;

 *
                             MyButtonClass
                                    |
                                    |
                    -------------------------------
                    |                             |
                    V                             V
            MyTextButtonClass             MyPictureButtonClass
