no korganizer alarms

[roberto <roberto03@gmail.com>]

Hello everyone,
i'm trying to get some appointments' alarms triggered by KOrganizer
but the following problems arose:
1. from menu i choose: "Actions"
2. then "new event"
3. in the panel i compose all fields like "date&time" and then i click
on "Reminder"
4. finally "Ok"

but even then the time of the fixed appointment goes by and no alarms
is triggered, i mean no popups, no sounds, nothing at all

has it happened to some of you?
maybe a bug??

thank you very much in advance
