In IE if I back swipe to return to the last page, there is a smooth transition and then the page appears to reload, returning to the top of the page instead of where you entered or tapped the hyper link to get to the page you were returning from. If you swipe from the bottom of the screen and then use the back arrow, you get a nice smooth transition to your previous page with no apparent reload. The page is rendered exactly where you would expect it. The inconsistency is very perceptible and annoying. Hopefully this is an issue handled in a near future update.
