Autodesk has made some enhancements to the Cursor in AutoCAD 2015. A minor improvement was the crosshair lines that used to run through the pick box have been removed to make it easier to view what you are selecting. You can still use the PICKBOX system variable or the OPTIONS Dialog on the SELECTION tab to change the size of the pick box and the length of the crosshairs in the Display tab (or the CURSORSIZE system variable) to your personal preference.
The major improvement to the cursor is the new Badges.
When you are selecting with Window or Crossing you will see the Selection badges appear near the crosshairs…
