Invincible shutdown buttons!

I booted into Vista yesterday to test something. It offered a bunch of updates to install. After they were installed, I got this:

Invincible buttons

I am not sure what shutdown buttons do when they look like this. I guess they are invincible, or something. Ha, I’m your log off button! You can’t kill me!

Yes, one of the updates installed was the ATI driver update, so I guess there’s some glitch somewhere in the driver update that makes some buttons be displayed like this… But hey, this is not some random driver that I found on the net, it’s the one that is officially suggested by Vista’s update!
