I have three tabbed docks, all are pinned to the top edge of the same monitor, all are always on top, and all positions are locked.
Today, after restarting my system, ObjectDock did not start. (see ** below.) So I started it manually.
All three of the tabbed docks were placed on the wrong monitor. I had to unlock them, drag them to the correct positions, and re-lock them.
Why? This seems like a bug to me.
(I wish there were a built-in way to backup and restore settings. Manually creating a copy of the settings folder and then copying them back is not a great user experience. But I will do it in the future.)
** Load at Startup IS checked. But I'm not too worried about it not auto-starting. My user account is messed up somehow. Auto-start of most/all programs has been a problem for months. I have to place links in the Global Startup folder to get them to work. (Not in the User Startup folder. Not in the Registry. I have asked and asked for solutions -- so many related registry entries can affect auto-start -- but none of the suggestions has worked. The only thing guaranteed to work is to create a different user account and start over again. That's too painful. So I gave up.)
Moved to ObjectDock area
