  Misunderstandings have occurred regarding the conclusions of the paper by S.
Arndt, W. Dappen and A. Nayfonov 1998, ApJ 498, 349. At occasions, its results
were interpreted as if it had shown basic flaws in the general theory of
dynamical screening. The aim of this comment is to emphasize in which
connection the conclusions of the paper have to be understood in order to avoid
misinterpretations.
