Not sure anyone else might be experiencing this. I just updated SL 360 over an hour ago. Now, I no longer can switch between Allow user to drag seekbar to Seekbar is read-only, or vice versa. I tried saving the SL file to a different file name, doesn't work. Close program, even rebooted the computer, still no affect. Whatever the setting for the seekbar was last saved on every file, I no longer can toggle to the other setting.
