Hello
Are you looking at eh value of the variable while the application is stopped or while it is running?
If you are looking at value when application is stopped, value of global variable must be updated.
Make sure to attach a reproducible case to demonstrate what is going wrong. You can use Help -> Pack and Go and let hte wizard extract the necessary information for the service request.
If you want to see variable changing while the application is running, you need to activate periodical refresh for the global data window.
Just click right on the global data window, select Mode -> Periodical and adjust the refresh period.
