I am working on Blueprints that represent dungeon parts with one static mesh for the aisle, corner and so on and then some decorative objects like torches, webs and so on.
When I place a new decorative static mesh in the BP and then select it and then for instance click on the scale icon I must click twice on the gadget that lets me scale the object in the viewport. The first click goes unnoced and will at best rotate the viewport. The second click is then captured correctly by the gatdet and allows me to scale a side of the mesh.
The same is true for rotating and moving the mesh.
