Thanks,
the first link opened a page where i thought I have to download something... But no, it started something which stopped the PC answering. After a while it gave a message something like (sorry, my translation from Finnish language, not correct terminology): "The command chain on this page stopped answering ..." and three choices: carry on, study the command chain or stop the command chain. Whichever i select, the action disappears.
I'm sorry, I must have done something wrong.
