Perfect. I had indeed hidden the dock area. Now it is fine again.
With regard to the snaps, I am happy to leave all snaps but grid, active most of the time.But, I would like to see the snap points show up on the screen. For example, a circle would have 5 markers, one for the circle's center, and 4 for its quadrants. Then I could locate a quadrant point more easily without having to zoom in to see the cursor "snap" to position.
