Are you using a mobile device? I find that it doesn't always render properly when I visit with my iPad, but it's usually not that bad.
I'd try switching themes. Switch to another theme and then switch back again.
Our postal service loves to pull that stunt all the time. Forget thorny bushes. If the steps to your front porch are too high (as in each step is more than some specified height), they will refuse to deliver your mail. We had an overgrown tree that was hanging over the walkway and they refused to deliver our mail because the postman would get wet after it rained. No I am not kidding. The tree was hanging low enough that he would have to duck under it.
Here they want to stop door-to-door delivery of mail completely, so they look for any excuse they can find.
I might be able to give you a hand with that. Basically the niftools exporter works for Oblivion without any messing around. If you're using 3DS Max, I'm not sure if you can use packed strips shape for the collision without crashing the exporter. Of course I don't really know what I'm doing, so it could be just me.

If he doesn't have a guide about video drivers specifically, then have a look at one of the game guides, like Oblivion. He will have a section on completely uninstalling video drivers in one of the game guides.
And I'm pleased to say not all cats are like that! My guy was mortified the one time he bit me. He was trying to bite the comb that was ripping a knot out of his fur and got my hand instead. As soon as he clamped down on soft flesh, he immediately let go with a rather concerned look on his face. A quick pat on his head confirmed that he wasn't about to lose one of his nine lives. And he got a quick rub on the sore spot to relieve the pain. Both mom and cat were much happier.
