I wonder if anyone can help me with this question or if it has been asked before.
When I have lots of entities I want to copy, move or delete from one part of my drawing to another, I hold the left mouse button down to start a window selection and drag it over what I want to select.
If when I want to select more entities in a different position I hold down shift and start another window, which adds those entities to my existing selection set.
The problem arises when I need to do another window selection that already has an entity I have selected previously in it.
What happens is the entities I previously selected become unselected, which isn't what I want.
Is there a setting I need to change, keystroke combination or is there no way to do just an accumulative selection, regardless of whether the entities are already selected?
Many thanks in advance,
Dahzee
