Thanks again Lyndel,

there is still a problem :
When the time is reached (3:55) {CF.widget ("A4","B","C").executeActions();} is running OK
but then there comes the error message "Busy playing actions"
and the periodic udates stop again.

The actions in CF.widget are as follows:
-Beep
-Delay 1 sec
-Jump Hilfstimer - new page
-Delay 5 sec
-Jump Timer _ Timers
-Delay 5 sec
-Jump Home

Might it have something to do with the jumps ?

I've also tried with scheduleActions instead of executeActions but then

the actions in the button A4 are running and running frequently without stopping.

Have a nice Sunday
Fischi
