I only rarely use Sync Lock. However, on my current project it keeps turning on (the slash marks show in the control panel of the timeline) without my knowingly having set it. Is there a shortcut I may be inadvertantly hitting that brings it on? Or is there something else in a setting that could be force reverting it?
One possibly useful detail is this project was started for me elsewhere on a PC-based Avid running the same version as mine - 8.6.1.
