I pushed out a minor update today that corrects a bug related to the new "no keyguard" settings.
There were instances where if you your screen off setting was "no keyguard" and the delayed action was simple or pattern lock, in some cases, the delayed action was not being applied due to some quirks in the Android system keyguard.
If you are still experiencing a similar issue, please contact me directly.

UPDATE: 4/11/2010 additional changes were made in version 2.1.6 to fix bugs related to "no keyguard" settings.
