Schedules stop activating about app-soundmanager HOT 1 OPEN

This is a great app.  I have had one problem, though.  I have six schedules for 
the notification volume.  Five of them execute on time, but one doesn't.  The 
ring volume, alarm volume and multi-medium volume have the same schedule as 
notification volume and execute properly each day (basically silencing the 
volume at the beginning of the work day and raising it to normal at the end).  
All the variables I can note are the same so I can't figure out why that one 
scedule won't execute.  I'm using a Motorola Droid and the problem has 
continued with both Android 2.1.1 and Android 2.2.

Sincerely,

Raymond Collins
