Lock screen doesn't activate.

Running CM10, (today's build [11/11]), and I've lost my lock screen functionality.

I've tried all the different lock screen options, and none of them activate when I try to lock the phone (via power button thingie on top).

I'm quite technically adept, but really out of my league as to what would even cause this. I've checked all the settings that I can find regarding lock screen delay, etc. Can't find anything.

Did some searching, but all the information I've found relates to Samsung phones. Not sure how it may operate differently on a Motorola device.

HALP!

You're probably better off asking in the CM forums.
