Update:
the same procedure works if I use tecnics>>settings>>Timed Operations>>Background tasks>>Hal routine and crashes if I use NewPeriodicTask2() to run the same procedure every 60/180 seconds (interval does not matter, crashes on the first run).
What I can see, RecordSave() is beging executed in both cases, but RecordStore(ContactCUr,false) fails with crash in Periodic task.


Any ideas why this happens?


With tecnics>>settings>>Timed Operations>>Background tasks>>Hal routine:
