Whenever Titanium Backup runs one of the scheduled backups, the screen no longer times out. It will dim, but never go off. This isn't just while the operation is running, either. For instance, I had a scheduled operation this morning at 4 a.m. At 7 a.m., the operation was completed, but the screen was still on (albeit dimmed). The only way the screen time out starts working again is if I kill Titanium via System Panel. Is this normal? What gives?
