Hi,
Most likely there is something wrong with your specific database or your LabVIEW DSC installation. I just used the Alarm & Event Query.vi in my machine and it seems to work fine, I can see all the alarms as well as events containned in the database.
You may considerer generate another database (change the logging directory) and see if the behavior goes away. Also, make sure you have alarms and events on that database.
I could run the Alarm & Query.vi by just openning its front panel and placing the correct database in the appropriated control.
