P.S. if anything, Heroes of Might and Magic III is glitching for me, instead of it, some kind of message appears... maybe it works fine for someone else.

by the way, it's strange, but after I play Battle for Wesnoth, all the symbols start appearing for me... that is, all sorts of notes, asterisks in the names of groups on VKontakte) and otherwise, only squares appear, in some cases asterisks.
