CeSetUserNotificationEx Help Please

Hello,

I am using:
Visual Studio 2008, C#
..net Compact Framework 3.5
Mobile 6 SDK
Mobile 6 device

My code compiles fine.
When I test the code with the event set to 3(ac On) or 4(ac Off) nothing
happens when I plug/unplug the power cord.
When I test the code with the event set to 1(time change) it works fine when
I change the date.

Am I doing something wrong???
Any help would be GREATLY appreciated.

Thanks,
Tia
