paintbrush it sounds to me like you have a bad install to be honest. I've had that happen quite a few times over the years of formats. I personally love Windows 8 so far. It's got a few quirks but since I discovered True Launch Bar my life is heaven with it lol.

Cheap little tool that is basically like a cross between a toolbar and a task bar. Lots of things you can put on it and you have full control over every aspect of what is on it. You can put shortcuts, folders, create a sort of Quick Launch Bar, clock, IP, weather, even a button for turning your computer off. There's a ton more, but those are the functions I use the most. It's like 13 bux or something like that, really cheap and worth every penny!
Outside of that being really the only problem I have with Windows 8 (file and folder access is more difficult without the True Launch Bar), it's working pretty slick for me. I even have it tied into Facebook so I get a popup if someone messages me so I don't have to worry if I only check my facebook every other week or so lol I won't miss the messages this way
I also love the new dual monitor system which allows you to see a different background on each monitor, simple thing I know, but a cool thing too. The Windows button puts you 1 button away from the Start Screen which I hardly use to be honest. I created folders on my True Launch Bar with categories to all the shortcuts I need/want/add so the Start Page is just a novelty for me for checking out apps that I don't really use either lol.
I dunno, I truly love it even though SirAge told me I'd hate it lol. Try that True Launch Bar tool and see if that will help at all
Other than that, I would truly think about a format/reinstall and see if that fixes a few of the quirks you're having cuz I retired my gremlins on Per's computer so I don't think he's sharing yet
