Yo lo tenía instalado, formateé la lap y ahora que quiero instalar de nuevo la sidebar pues según hace todo el proceso, sin ambargo cuando le doy doble click al sidebar no parace la barra,¿a que se podrá deber este asunto?, la única barra que me dejó instalar es la de Thoosje pero lo malo de esta otra sidebar es que no puedes agregar gadgets. Si alguien me puede decir como le hago para volver a tener la otra sidebar(la que si le puedes agregar los gadgets desde la página oficial). Gracias y saludos desde Puebla, México.
