I just upgraded my Ipad to io5 and all went well apart from the fact that before i could minimize the windows and kept all in the background. Now with io5 I can't do it any more, when I open a 2nd window the 1st one still appears in the toolbar but that is it, no more than that. Can anyone please tell me if there are any apps that will do it. I love my Ipad to bits, there's nothing like that to me, but the 'single window' problem is driving nuts. Any advice very welcome.
