I'm using version 3.103.0.0
I think the change happened at the last upgrade. The upgrade resulted in OC being removed form the Start menu so I added it again and then the list was missing.
I just tried remove from Start and added it again and still no list.
I just deleted an OC saved window and no difference
I just created a new OC saved window and still no list.
The list is present if in the "Open new window" dialog in a running OC, but not on right-click the OC icon in the Start menu.
