I use gestures on my iPad all the time. I like to keep my Mail, Safari app, maybe a book, open all the time and simply use the '4-finger' gesture to swipe back and forth. Because I use it this way I tend to keep my multi-tasking area pretty clear. So when I use an app (FaceTime for instance) I like to close it out of the multi-task area so I don't have to scroll through it to get to Mail (or something else). Here's my question/issue: if I use an app (let's say FaceTime) and I finish the call I swipe to another open app and perform the gesture to expose the multi-tasking area. I then hold down the FaceTime icon, get the minus sign, and close the app. But if I then swipe back the app is still there and opens, in other words, it doesn't seem to actually close. This happens on any app I use. If I try to close it out in this manner it doesn't seem to actually close. If I go back to the Home screen it will close. Is this the way it's supposed to work or is this a bug? If its not a bug, then why is it set to work this way?
