Many times I make a box around a collection of elements and want to select all the elements within that containing box, but not the box itself.
If my selection includes the center of the containing box, it will select the box.
I never had this frustration with CS6 so I think they may have changed it for CC. I think previously it would only select the containing box if it had a fill.
Changing the preferences to only select by path only does not fix this behavior.
Is there any way to change this behavior?
