After using the color picker to pickup a fill color, the cursor does not come back and the color picker color also dissapears.
Enter Layout Mode, open inspector, click on the fill color, choose other color... select the color picker droplet, select a color somewhere. As you click no more cursor.
Move mouse all the way up then click. (Clicking somewhere in the menubar brings the cursor back)
