Phew! Three hours later and I've finally finished reading this forum. That's a chunk of my life I'll never get back...I feel like I know some of you people - can't wait for the movie to come out, who will play Chronicon Helveticum - back in the day I would have said that guy who played Lou Grant, but nowadays I'm thinking Morgan Freeman?
I've got an Ipad Air and just noticed the problem these past couple of days, and after hoking about here and veering off to some of the links I've managed to stop the behaviour at least on my bit of kit (and please forgive my lack of tech savvy / accurate terminology).
I play Scrabble and switch to Safari/Google/ScrabbleFinder web page for cheats. Just switching between these two things was a two minute wind-up of gargantuan proportions, the word typed in the search box on the web page would be gone when I went back to Scrabble then back to the web, and Scrabble would refresh and hang instead of just reappearing instantly on my game board, just so so time consuming and annoying. So I typed a search in Google and here I am.
Anyway, the bottom line is, by doing the thing below, this doesn't happen any more, the search words stay put and the Scrabble board is there straight away, no refresh etc.
I didn't know about the double click on the home button thing that in itself is a pyrotechnic revelation. There it all was, EVERYTHING that had occurred since I got this thing about a month ago - camera, Angry Birds, Skype, on and on and on. I know from reading here that this isn't necessarily a hard cached footprint of all activity, just a minuscule snapshot of apps (etc) used, but it is very interesting that after I flicked them all to the top to get rid of them, the machine started working in a fit for purpose way again, searches now stay put, multiple web page tabs remain the same and don't refresh and Scrabble goes straight to the game board without an initial refresh/reload.
I'm convinced this is a memory issue, 1gb RAM is not a lot and it's interesting my problem went away when I closed down all those apps. I know ideally we would be able to have multiple apps open at the same time all working freely and smoothly at least to Apple's suggested faux multi-tasking levels, but this is the real world and I don't think the Ipad is meant for that. Keep your cache clean, disable memory intensive settings and keep killing apps you're not using, and do a total(ish) kill every day then you'll have enough memory for the few apps you need or want to use in the moment.
For what it's worth, I think the solution about turning off auto brightness seems to make sense if you think there is a glitch but mine was never turned on and I got the problem all the same.
