Origin Ver. and Service Release (Select Help-->About Origin): 8.6.0 (64bit) Sr3 b99 Operating System: Windows 7 Proffesional
Afrer some time using OriginPro Sr3 the checkbox hide/show layer in window plotdetails-layer properties dissapared, so I can just use "old method" to hide /show layer- right mouse click->hide/show. Reinstall don't help
Right-click under the hierarchy in the left panel of the Plot Details dialog, beneath the text in the empty white area. A menu will appear that says "Show Checkboxes". My guess is that now you are seeing icons. If you right-click again the menu will say "Show Icons".
