Query: Spaces of continuous functions over Dugundji compacta   We show that for every Dugundji compact $K$ of weight aleph one the Banach
space $C(K)$ is 1-Plichko and the space $P(K)$ of probability measures on $K$
is Valdivia compact. Combining this result with the existence of a non-Valdivia
compact group, we answer a question of Kalenda.
