I met some problems on my windows phone app of the BackKey.
For example, in page1, i press a button to navigate to page2. Then i press a button in page2 to navigate to page3.
At this moment, i press the BackKey, and the app successfully back to page2. Then press the BackKey angin, it back to page1.
But when the OnNavigatedTo event of page1 is done, the app automatically back to page3!!!
Why Page3 is still in the BakcStack? Can anyone tell me what happened behind?
