Well, so much for Out of Print cases. I went back to the Chapters store where I got the first one, and they were nice enough to let me try my Glo in another one. Which had the same problems. So I got a refund (no arguing or anything, great customer service) and bought this one instead. (10$ cdn, though, not the price on the website)

It says it's for Kindle, but it fits the Glo quite well. The only thing I can't access is the micro SD, but that's not a big deal for me since I rarely do anyway. Now to get a small magnet and see if I can make my own sleep cover!
