I've been trying to get SL to work on my sisters computer, but it hasn't been working. Whenever it opens, I'm unable to click and login. It's frozen. The odd thing is, if I minimize it and max it again, whatever I had clicked will suddenly have had effect. SO, I would enter my login information, unable to see it, then minimize and maximize it, and it will have shown up. Then I can click login, min/max it, and it will log in. Think like, weeping angels. It won't move while I'm looking. She uses a windows 8, ASUS VIVObook, if that helps. I can't find anyone else with this problem and it's very puzzling. I've already uninstalled and reinstalled it a few times and restarted the computer.
