Can anyone confirm this:
I see strange multitasking behavior of metro applications. In 8.0 when you swipe from top of screen, you close application. Now if you do the same, application seems closed and if you start it again if will loads from start. But, if you close application then open task manager you still can see this application on first tab and if you double click on app, you will be switched to it and application will be at the point of time when you close it. For example run calc, enter some number and make calculation. Close calc, run task manager and double click on calc. You will see that you numbers are still there. Same for games. All those app are still on memory. I don't know is this normal behavior for 8.1, but for me it looks lie bug. If I close app, it must be closed.
