I tested the B4J example of the AS CalendarAdvanced, but I get an issue:
If I disable the Expandable option in Designer, I get a black screen.
If I click and move the mouse, I can see the calendar, but if I release the mouse, the calendar is missing.
I don't know. I downloaded the sample project, disabled the property and there is no black screen. Make sure that all libraries that the calender accesses are up to date. You can find the list in the libraries thread.
