Alexey,
Yes that is what I did...
There are two options that you can do is 1) use Tools --> Orthomosaic --> Update Orthomosiac
The second one is right click on the Orthomosaic, in the workspace, right click on Update Orthomosaic
So I tried that and it is greyed out....even I use to select all of then....
P.S. I made a backup from yesterday.
I can see what you mean selection is when you selected a polygon and then you see red circles around the polygon show up and then right click on the Orthomosaic and I can see that Update Orthomosaic came on again...
so I can see it is working again...
Thanks for clarified again ...
