I think one of the issues is once you close it and than try to swipe in other apps the closed one pops back up as a swipe in app. atleast for me it does. So the optional removing from history is needed. Thx
Bug to report- while in IE I have it opened maximized but not full screen- still have X, min and max button showing, if I rt click my mouse it will pull up tab menu but screen goes blue and blank. Love this app- would love to see the min/max buttons etc a little more touch friendly. Running Surface pro, also have object dock loaded if that makes a diff.
