just to follow up, I uninstalled everything Stardock and ran for a few weeks that way. After last W10 update, I reinstalled everything. In between I had a problem, in that the few icons I have on my desktop were divided between my two monitors. After reinstalling, I still had the split, so I dragged them all into new fences. With each new boot, additional icons keep showing up. I keep dragging them into a fence. Other than that, Object Desktop seems to be running quietly.
Thanks.
