Summary:
On first entering a page that uses the AlarmSetQuery() function in the Page Entry event, the query will not work. Why? 

Solution:
The AlarmSetQuery function is run before the alarm functionality for the page has had time to be setup.

To avoid this problem, put a Sleep() function in front of the AlarmSetQuery() function to allow the alarm functionality time to be set up. A value of 500mS should be sufficient, though experimentation on a reliable value is recommended.

CIT has confirmed this to be a problem in Citect for Windows version 5.30. We are researching this problem and will post new information here as it becomes available.
