But why it takes only microseconds after starting the game and minute after say one half a hour? That is strange...
Edit:
I was wrong about it. It takes 15 seconds after starting the game, but only with stats window open. What is really strange, is, that this was not problem in version 0.4, even there was not so different xml file.
Additionally, why this problem occurs only while the actually used skill is trained? When it's untrained, the window appears imediatelly.
