DAZ gizmo selection/display issue

markm92126_281737cb9f

Suddenly, the highlight/selection point for the gizmo to move or rotate an object is shifted so that the cursor has to be about .75 inch on-screen BELOW the actual arrow, but ONLY in the main viewport.. it works normally in the aux. viewport (i.e., the cursor highlights the arrow when directly on it, as it should). Current version of DAZ, running a MAC/Mojave. Always worked normally, then suddenly didn't... mut be missing something. Any ideas?
