Hi!
  Update from today morning: konqueror now just crashes on the site.
                                          With regards, Pavel Troller

> per second on a quick machine). It doesn't start just when loaded, some
> manipulation (scrolling, trying to follow a link) should be performed first.
>   - Trying to follow the link to the full article from the headline
> (a red link named "Pokracovat" at the bottom of the headline box) causes
> that the link just disappears and is not followed. When the place where the
> link was is clicked again, the whole headline disappears, just a grey box
> remains there.
>   There are some JS effects which are not found on other pages so I think
> there could be the problem.
>   It's a regression of about 3 - 5 days; formerly, konq didn't have any
> problem viewing this site for a relatively long time.
