Issue Details

When a VI is running, I cannot scroll on an array indicator with the mouse wheel. If I try to scroll down by clicking and dragging, using the mouse wheel, the array resets to the first position. This behavior does not occur on array controls. 

Solution

This is a known bug in the scrolling system that affects certain earlier versions of LabVIEW. A recommended workaround is to use an array of controls set to a disabled state, and update the values programmatically using a property node or another method.

The issue was tracked under ID 680417 and has since been resolved in LabVIEW 2023 Q3, as documented in the release notes.
