Cannot edit vertices, edges or faces I cannot edit vertices, edges or faces because of the 3d cursor.
When in edit mode with the appropriate vertex, edge or face icon selected I try to click to select, say a vertex which I want to drag to resize and all I get is the 3D cursor which cancels the drag edit action.
You can change the mouse button with which you click in the Preferences/Input and change (select with) to Left, it is set to Right by default
