Ah, well it's not doing that
Hmm, I wonder if uninstalling Schap's Advanced Configuration Tool had anything to do with... but I don't know why that would affect anything else. It was working a few hours ago; I only just noticed the change. A soft reset didn't seem to change anything.
EDIT: Uh, when I lock my phone and then press the sleep button, and THEN slide open the keyboard, it automatically unlocks and wakes the phone. But if I don't lock it and just press the sleep button and try to slide open the keyboard, it doesn't wake. Where do I mess with the settings for this?
