It's just in a special mode that is a feature that few seem to know about.
Blog post about it if you want to turn it off.
I'm not really sure how to describe this, but when I hit ctrl+alt+delete, it no longer has the blue bar at the top where i can close it. It doesn't even have the tabs to change from tasks viewer to processes, networks, etc. It is just a gray box that shows the open tasks. It wasn't always like this. Any ideas what is wrong? Thanks
