Have not done many part files utilizing tool changes in my first 3 months using my new machine.
Problem:
Had SB3 freeze up when switching temporarily to keypad in order to zero the new bit in middle of part file.
First time, thought it was jump drive interrupting windows, but it's happened again w/o jump drive plugged in.
Likely some really simple setting in the program, but with my newness to machine, don't know what to do to remedy.

Anyone have a clue?
