Fenixp: Nope.
This is how the combat is :D. However, I've encountered Weclock's bug a few times as well.
However, if you want your game to be nice and polished, rather play Mass Effect - technologically great, not so great story-wise and character-wise though (Witcher sure has one of the best characters in gaming history... IMO)
Weclock: I'd reccomend you try and give the game another shot: A loooong shot. You seem like my friend, who absolutely hated technological inperfections in the game, and, because of that, game itself. However, he finished the game 2 times now, just because story was so good. As he said, he won't ever like The Witcher as a game - however, he'll always love it as a story. Maybe you'll end up the same...
Edit: I sure like word 'however'...
Oh I'm still gonna play it.. and if that's a bug, you might want to help me out, because it's happening all the time.
