MapInfo Pro ruler tools drops nodes without clicking left mouse button as expected

Products affected: MapInfo Professional™, Discover™

Issue

When running MapInfo Pro 15.2 64-bit and using the Ruler tool, after clicking the left mouse button to start the measurement process, multiple nodes are being dropped without clicking on the left mouse button.

Typically, only when left-clicking on the mouse button would a node be created.

Cause

Mistakenly clicking on the letter "N" on the keyboard can put MapInfo Pro into "autonode" mode.

Resolution

UPDATED: December 6, 2019
Clicking on the letter "N" again will turn off "Autonode".
The status of "autonode" is visible at the bottom of MapInfo Pro - if the word "AUTONODE" is visible, then Autonode is enabled.
