I don't have this license at home so I could be imprecise. Activate More options as I show you in the attached image.
It should appear the flag 'deselect automatically'.
I hope it is what you need.
Thanks Cesar, I looked into that but that is already set to 'more'....
Anything else I can try?
On selection toolbar the command to turn it off and on is there. It is also then on the mini-selection toolbar and I am only showing it on the selection toolbar.
the pic which you have sent, I can see that when you hover your mouse cursor over the command, it shows the little dialogue box where command and what it does is shown.
However in my case, I can only see the command only.
If you hit (CTRL)+1 you get the menu to customize the layout, Do you have tooltips turned on?
