Hello. I receieved my DK2 yesterday and have been having a lot of fun with it. One thing I started noticing when I was trying out some of the demos, is that sometimes when I quit a demo, my windows goes crazy. Every window that is open is just pure black. My start bar shows nothing but the start menu, and when I click on that it is just a solid black box. If I hit ctrl-alt-delete there is no options that show up. If I press enter the task manager pops up, but it is again just a big black box. I have to restart the computer for things to work again. This wasn’t a huge deal with the demos, but since I started using perception and vorpX, it does it every single time. I’ve tried googling it and have found nothing. Any ideas?
