Windows 8 also brings a very transparent tool for examining global indices, where you can also optionally keep track of the value of individual shares.
If you don't want websites tracking you, and you don't want the pages you view to be saved in browse or search history, you need to active the incognito mode and this is what you need to do.
If you experience an Mac OS X program to freeze and you cannot exit it by clicking quit or using a keyboard shortcut, you can always force it to quit using the Activity Monitor.
