Have you ever accidentally double clicked on the task manager and lost all means of closing it? I did this the other day and could not for the life of me figure out what had happened to it and where the control bar went and what to do to make it go away! Somehow, I managed to double click on it again in my frustration and realized what was going on.

As far as I can tell, it is impossible to close the task manager once you have done this. But really all you need to do is double click on it again and the control bar comes back and all is normal again.

I can't understand why this would be a "feature". It's awfully confusing.
