Not to be all 'captain obvious' here, but...Just close SB3. I don't understand the big deal. If you are paranoid, park the tool at a round number (E.G. 24,12) and close out SB3. Write down those numbers if it makes you feel better. As long as the control box is on, you will not lose position or mess anything up in SB3...and no more DRO covering up your toolpath tab. The DRO is modal for safety reasons...and yes it is a pain if you want to tweak your file. Just close it...Solved.
