Really there is no other way to describe what it does. i will be typing an email out either composing a new email or replying or forwarding another email and it will reandomly cange pages back to the inbox with no prompt or anything. in the browser i have a forward button as if the back button has been clicked. if i click forward it brings me back to the email where i left off.
here is a video of it actually happening. around 1:55 it actually happens. after it went to inbox i accidentally hit back instead of forward first which is why it went to a blank compose window, but as you can see forward brings you back to where you left off.
