Norton 360? I don't know if anti-virus software alters the recycling bin, and is causing ObjectDock to act differently. Anti-virus software has been known to cause issues.
If any AV was going to cause issues it would be Norton.
I dumped them almost 20 years ago, still with about 6 months of sub... simply because they were incompetent.
I moved on to Bitdefender...all good until they were too slow to be compatible with Win 7, so moved on yet again to Kaspersky and have stayed there ever since [probably over 15 years]...
