There's a bug in the ViewGantt (List index out of bounds(n) ).
Situation: The screen shows 20 resources, but there are more when you scroll down. The items wich are in the initial first 20 resources you can move around in the scheduler. But when you try to move an item wich is not initially in the screen results in ar error. The number of the index is the number of the resource.
If there's no scrollbar and all the recources fit completely in the scheduler there's no problem.
I included a sample program. Just scroll a bit down and try to move an item (up or down).
The version of the scheduler is 12.2.3
