If activating "Edit Instances" mode, the following viewport navigation actions execute a selection/deselection of instances when the cursor is above the scatter:
- Zoom
- Pan view
- 2d pan zoom mode
Apparently inherited error: when using a 3D mouse, the selection happens at every movement in the center of the viewport. In this case, you are not even able to use the standard move transform type-in. Using Forest Pro and similar, subobject/instance selection works as it should.
Good Luck
