I hope I have all understand because I am German.
What do you means with "Could be for SP3 updated"???
I happens with all links.
I click on "Favoriten", then I move over a folder and sometimes K-Meleon freeze.
Its not only when I click on a link. It happens when I moved over a folder/link too.
I have installed Win XP SP3 since December 2008.
It worked good.
