Screensaver auto-lock engages while typing!

Yes, it has become quite the irritation, most recently! I can be in the middle of typing something, and all of a sudden, my screensaver lock engages. Sometimes it's worse than other times. I run FastAccess Face Login, but have concluded the program isn't conflicting, or causing the problem. My screensaver settings have been set accordingly, but I can't figure out why this happens. Any insight or advice would be appreciated.

Possibly the best way to solve this problem, with the least effort, is a system restore.
