Rhino 6 "create backup (.3DMBAK) when saving" uncheaked still saves



Rhino 6 "create backup (.3DMBAK) when saving unchecked in options>files. Still saves every time. No big deal, but along with opening .stl files in Rhino 5 instead of 6 (double click on .stl) no matter if I choose (Open With Rhino 6), seems to be something to fix (bugs). ThanksCapture


Can you reset the file association for .stl to V6 via

Control Panel\Programs\Default Programs\Set Associations




Did that already. Did not work. Thanks
